To complete a reservation, the Lead Guest must provide full legal names of all guests, nationalities and dates of birth, passport details, arrival and departure dates and flight/ferry details, dietary requirements and special requests, a valid email and phone number, and emergency contact details.
Villa Onu reserves the right to refuse, cancel, or amend any reservation containing incorrect, incomplete, or fraudulent information, or that remains unpaid past the applicable payment deadline.
Group bookings must be made by a single Lead Guest who accepts responsibility for the group's compliance with these Terms.
03 Rates, Inclusions & Exclusions
All rates are published per room or per villa, per night, based on the season (High or Shoulder) and the chosen package (Full Board Experience or Room/Villa Only).
Rates are dynamic and may change at any time without prior notice. The rate applicable to a confirmed booking is the rate stated in the written booking confirmation.
Full Board Experience rates include accommodation, daily breakfast, lunch and dinner, soft drinks, tea and coffee, selected activities and experiences as listed, and housekeeping.

Unless explicitly stated, rates exclude: airfare and ferry tickets, transfers, travel insurance, surf charters and fishing trips, alcoholic and premium drinks, laundry and personal expenses, new government taxes or service charges, and tips.
Villa Onu reserves the right to introduce or adjust government taxes, service charges, or levies in accordance with Indonesian law.
04 Payment Policy
More than 60 days out: 30% deposit · balance due 45 days before arrival.
Less than 60 days out: 100% payment due at the time of booking.
Bookings made more than 60 days before arrival: A non-refundable deposit of 30% of the total booking value is required to confirm the reservation. The remaining 70% balance must be paid no later than 45 days prior to arrival.
Bookings made less than 60 days before arrival: 100% full payment is required at the time of booking.
If payment deadlines are not met, Villa Onu reserves the right to cancel the booking and retain any payments already made.
All bank transfer fees, payment gateway fees, currency conversion fees and credit card processing fees are the responsibility of the Guest.
Credit card payments may incur an additional processing fee of up to 3.5%, disclosed at the time of payment.
Villa Onu does not store credit card details. All card payments are processed through secure third-party providers.
05 Currency & Exchange Rates
Villa Onu operates primarily in Indonesian Rupiah (IDR). All official invoices and final settlements are issued in IDR unless otherwise agreed in writing.
Rates displayed in USD, EUR, AUD, or other currencies are approximate conversions only and may fluctuate due to daily exchange movements, payment provider rates, bank processing rates and weekly currency adjustments.
Villa Onu reserves the right to update currency conversions at any time. Final amounts may vary slightly from prior estimates.
Refunds, where applicable, will be processed in IDR. Any losses arising from currency conversion at the time of refund are the responsibility of the Guest.
Cancellations & Changes
What happens if your plans change before arrival.
06 Cancellation Policy
Due to the remote location, limited capacity and operational planning required for a stay at Villa Onu, the following cancellation policy strictly applies to all bookings.
More than 60 days before arrival: 70% of the total booking value is refundable. The 30% deposit is non-refundable but may be converted into future stay credit valid for 12 months, subject to availability. All bank fees are non-refundable.
Between 30 and 59 days before arrival: Payments are non-refundable. 50% of payments may, at Villa Onu's discretion, be converted into future stay credit valid for 12 months.
Less than 30 days before arrival: All payments are non-refundable and may not be refunded, credited, rescheduled, or transferred to another guest, regardless of the reason for cancellation.
The applicable cancellation tier is determined by the number of days between the date Villa Onu receives the written cancellation request and the current confirmed arrival date. Where a booking has previously been rescheduled, or has been paid in whole or in part using future stay credit, the current arrival date applies — not the date of the original reservation.
Early departures, unused nights, missed ferries, delayed arrivals, "no-shows", or changes during the stay are non-refundable.
Cancellation requests must be made in writing via email and are only valid once acknowledged in writing by Villa Onu.
Villa Onu strongly recommends comprehensive travel insurance covering cancellation, interruption and delays.
07 Reschedule & Modification Policy
Reschedule requests must be submitted in writing more than 60 days before arrival, include a valid explanation, and be approved in writing by Villa Onu.
Medical or emergency-related reschedule requests within 60 days may be considered at Villa Onu's discretion and may require supporting documentation from a hospital or licensed medical professional.
Approved reschedules are valid for up to 12 months from the original check-in date, subject to availability, may only be used once per booking, and cannot be exchanged for cash, credit, or refund.
If future rates are higher than the original booking value, the Guest is responsible for paying the difference.
If future rates are lower, or if promotional offers become available, previously confirmed bookings cannot be adjusted, refunded, or credited based on newer pricing. Promotional rates apply to new bookings only.
If the future stay value is lower than the original booking value, the remaining balance is forfeited.
Modifications to guest names, room categories, or dates within the same booking window are subject to availability and Villa Onu's written approval.
08 No-Show Policy
A Guest who fails to arrive on the confirmed check-in date without prior written notice will be considered a "no-show".
No-show bookings are fully non-refundable, regardless of the reason, and the room may be released after 24 hours.

While the Mentawai Islands are renowned for world-class waves, Villa Onu cannot guarantee wave size, quality, or consistency, weather conditions, visibility for fishing or snorkelling, or the ability to reach any specific surf break.

17 Ocean Activities — Assumption of Risk

Guests participate in all such activities entirely at their own risk and accept responsibility for their own safety and physical condition.
Guests must follow all safety briefings, instructions and directions provided by Villa Onu staff, boat captains and local guides.
Spearfishing, freediving, and surfing at advanced reef breaks are recommended for experienced guests only. Villa Onu reserves the right to refuse participation if a guest's skill or experience is deemed insufficient for safety reasons.
To the maximum extent permitted by law, Villa Onu and its team accept no liability for accidents, injuries, illness, death, loss, or damage suffered during participation in any activity.
Guests acknowledge that medical facilities in the Mentawai Islands are limited and that emergency evacuation may take significant time.

In such events, Villa Onu will use reasonable efforts to communicate promptly with affected guests, offer to reschedule the stay within 12 months subject to availability, and reduce or waive change fees where reasonably possible.
