Which channel should you use to contact Indonesia Juara Trip for Sumba?
Two channels reach the same reservations desk. A third, the short form further down this page, feeds the same email inbox.
| Channel | Best for | What you get back |
|---|---|---|
| WhatsApp — chat with +62 811-9941-919 | Quick questions, month checks, voice notes, villa photos | A short reply in the thread, then a written itinerary and quote |
| Email — sales@indonesiajuara.asia | Detailed briefs, groups, company travel, anything needing an invoice trail | A structured proposal with routing, resort options and inclusions |
| Short form (below) | Drafting everything once, from a laptop | Your message lands in the same inbox as email |
Pick one channel per enquiry. Sending the same brief on both creates two threads, and the desk has to merge them before it can answer.
How fast does the desk reply?
The reservations team works from Indonesia on Central Indonesian Time (WITA, UTC+8). Short WhatsApp questions sent during Indonesian working hours usually get a first human reply the same day. Overnight messages from Europe or the Americas are picked up the next Indonesian morning.
A full itinerary with resort pricing takes longer, because room availability is not ours to give. The desk asks the hotel, waits for written confirmation, then builds the quote. Allow one to two working days in most months, more in June to August when Sumba’s small high-end room supply makes hotels slower to confirm.
No reply time is guaranteed. If two working days pass with no answer, resend on the other channel and mention the date of your first message.
What should your first message include?
A complete first message gets you a plan instead of a list of questions. Include these eight items:
- Dates or month — exact dates if you have flights, otherwise the month and how flexible you are.
- Nights on Sumba — anything from 3D2N to 8D7N. Three or four days stay on one side of the island; seven or eight can cross from Tambolaka to Waingapu.
- Party — adults, ages of any children, and who shares a room.
- Resort tier — NIHI Sumba or Lelewatu (both in Wanokaka, West Sumba), Cap Karoso (Kodi, Southwest Sumba, about 50 minutes from Tambolaka by the resort’s own estimate), Maringi Eco Resort, a boutique villa, or “advise me”. Hotels are accommodation options, not partners; availability depends on the hotel.
- Arrival airport — Tambolaka (TMC) for West and Southwest Sumba, Waingapu (WGP) for East Sumba, or both for a cross-island route. Bali to TMC is a short domestic flight; schedules change, so send flight numbers rather than assumed times.
- Interests — surf, megalithic villages, waterfalls, horses, the eastern hills, or mostly the resort.
- Budget band — per person, marked land-only or including the resort. The two are quoted separately.
- Special notes — honeymoon, dietary needs, mobility limits, drone use (village drone fees around IDR 200,000 per the August 2026 fee guide).

Which trip lengths and prices can you ask about?
Indonesia Juara Trip’s published land-only ladder (luxurysumba.com/sumba-trip-cost, as of 2026) is shown for orientation only and excludes the resort. Totals including a resort are never published here; they arrive as a confirmed quote after the hotel confirms.
| Duration | Where it works | IJT land-only, per person (as of 2026, excludes resort) | Total with resort |
|---|---|---|---|
| 3D2N | One side only: West/Southwest or East | Quote on request | Confirmed quote |
| 4D3N | One side only | USD 390 / 490 / 570 | Confirmed quote |
| 5D4N | One side, or West plus Central | USD 459 / 700 / 850 | Confirmed quote |
| 6D5N | West, Central and a taste of East | USD 570 / 1,020 | Confirmed quote |
| 7D6N–8D7N | Cross-island: TMC in, WGP out or reverse | Quote on request | Confirmed quote |
The figures per row are IJT’s published tiers; the desk will say which fits your route. For NIHI Sumba, the resort’s public rates page states room rates exclude a 21 percent government tax and service charge, and its 2026 price document (March 2026) quotes in IDR. The resort portion of your quote reflects that. Lelewatu and Cap Karoso publish their own terms, which the desk passes on unchanged.
How does booking work after you contact us?
- Brief — you send the eight items above by WhatsApp, email or the form.
- Plan — the desk returns a day-by-day route with resort options, inclusions and exclusions, usually within one to two working days.
- Hold and confirm — you pick a version; the desk requests availability from the hotel. The hotel’s written confirmation and terms govern the room. Transfers and driver-guides are arranged via vetted licensed local partners.
- Quote and deposit — a written quote shows the land portion, the resort portion and the deposit and cancellation terms. Nothing is booked until you confirm in writing.
- Pre-arrival pack — driver-guide contact, airport pickup details, and the cash fees to expect: airport tourist tax IDR 50,000, village contributions IDR 20,000–50,000, lagoon and waterfall entries IDR 20,000–200,000, per the Sumba fee guide updated 19 August 2026. Transiting Bali adds its IDR 150,000 tourism levy.
Prefer to send a short form?
This form opens in your mail app addressed to the desk. Nothing is stored on this website.
When is the best time to get in touch?
Earlier than you think, if you want the dry season. Sumba’s dry months run roughly May to October; June to September is the sweet spot most Sumba planners name, and those months need advance booking of villas, cars and guides because high-end room supply is small. September and October bring fewer visitors and somewhat lower prices. For January or February, say so up front: mud and swollen rivers stretch West-to-East transfers, so the desk will keep a 3-4 day trip on one coast.
What happens if something goes wrong while you are on Sumba?
Travellers already on the island reach the same WhatsApp number, and their messages jump the queue ahead of new quotes. The pre-arrival pack also carries your driver-guide’s direct number, which is the faster line for a missed pickup, a flooded river crossing or a change of plan on the day.
For a medical emergency, call the resort’s front desk or your driver-guide first; both know the nearest clinic and the road time to Tambolaka or Waingapu. The desk then handles rebooking of transfers and, where the hotel permits, date changes to rooms. Travel insurance that covers medical evacuation from a remote Indonesian island is strongly advised; the desk does not sell insurance and is not a licensed adviser on it.

Frequently Asked Questions
What hours does the Indonesia Juara Trip desk answer Sumba enquiries?
The desk answers during Indonesian working hours on WITA (UTC+8), Monday to Saturday. A message sent at 22:00 in London lands at 05:00 WITA and is normally read within the first hours of the working day. Sunday and public-holiday messages are read, but replies can slip to the next working day. Same-day changes for travellers already on Sumba take priority over new quotes.
Should I send the same enquiry by WhatsApp and email?
No. Choose one channel and stay on it. Duplicate briefs open two threads that the desk must reconcile before replying, which slows the first answer. If you have not heard back after two working days, then switch channels and quote the date of your original message so the team can find it.
Can Indonesia Juara Trip book NIHI Sumba directly for me?
The desk requests availability and rates from NIHI Sumba on your behalf, the same way it does for Lelewatu, Cap Karoso or a boutique villa. NIHI Sumba is an accommodation option, not a partner, and the hotel’s written confirmation and terms govern the room. Indonesia Juara Trip is not the resort’s official booking office and does not hold an allocation of rooms.
Why is the resort price never shown on this website?
Because the resort sets it, not us. NIHI Sumba’s public rates page states that room rates exclude a 21 percent government tax and service charge, and its March 2026 price document quotes in IDR, so the figure changes with season, room category and exchange rate. The desk quotes the land portion from Indonesia Juara Trip’s published ladder (as of 2026) and the resort portion from the hotel’s written confirmation, then shows both lines separately.
How much cash should I carry for village and site fees on Sumba?
Budget for the airport tourist tax of IDR 50,000, village contributions of IDR 20,000 to 50,000 per village, and lagoon or waterfall entries of IDR 20,000 to 200,000, per the Sumba fee guide updated 19 August 2026. Drone use in villages adds around IDR 200,000. ATMs are limited outside Tambolaka and Waingapu, so withdraw before leaving the airport town; the pre-arrival pack lists the fees your specific route will meet.
