How to Time Hotel Bookings on a Thailand, Vietnam and Bali Trip

A two- or three-week loop through Thailand, Vietnam and Bali is one of the classic Southeast Asia trips. The flights between them are short and the hotel choice is huge. What catches people out is the timing. Each country has its own peak dates, its own building boom and its own quirks, so a booking plan that works in Bangkok can go wrong in Phu Quoc or Ubud.

Here is how to decide when to book each stop, and when a brand-new hotel is a bargain or a gamble.

Why timing matters more than star ratings

On a multi-country trip, you are not booking one hotel. You are booking a chain of them, each tied to a flight. If one stop is overpriced, fully booked or still half-built, the whole route shifts.

So start with the fixed points. Lock in anything tied to a festival, a public holiday or a peak week first. Then fill the gaps with flexible bookings you can change as your route firms up. Star ratings matter less than whether the hotel is in the right place on the right night, and whether you can cancel if you need to.

Thailand: book the big dates, stay flexible on the rest

Thailand’s high season runs through the cooler, drier months from around November to February. This year it is shaping up a little differently. Local tourism leaders in Pattaya said in early November that hotels had not yet seen the advance bookings they usually see months ahead, partly because airfares to Thailand have risen by an estimated 30–40%.

For you, that cuts two ways. Outside the busiest dates, many beach hotels may hold rooms open longer and could offer better deals closer to arrival. But the big dates still sell out. Tomorrowland’s first Southeast Asian edition runs from 11 to 13 December at Wisdom Valley near Pattaya, and hotels in the area have reported a jump in bookings. If your trip overlaps with a major event, Christmas, New Year or Lunar New Year, book early.

A practical split: book your Bangkok nights and any event dates as soon as your flights are set, then keep beach stays on free-cancellation rates and check prices again two to four weeks out.

Vietnam: new hotels, good value, and one island to watch

Vietnam is opening hotels at a fast pace, and that often works in your favour. A new property has no reviews yet, so it tends to price keenly in its first months to attract guests. If you are flexible, an opening offer can get you a far better room than you would normally pay for.

The catch is that new hotels do not always open on time, or fully. Pools, spas and restaurants sometimes follow weeks or months after the rooms. Before you book anything that has just opened, email the hotel and ask what is actually working.

Phu Quoc, the island off Vietnam’s southwest coast, needs extra thought. It will host the APEC leaders’ summit in November 2027, and developers are racing to finish hotels before then. Consultancy CBRE expects the island’s hotel stock to grow from about 19,000 rooms to about 31,000 by 2030. If you want a sense of what is being built on Phu Quoc, Asia Hotelier has tracked the new supply and what it could mean for prices after the summit.

What that means for your plans:

• Avoid summit week. Large diplomatic events take over hotel inventory and tighten security. If you are planning for late 2027, check the confirmed APEC dates before you book.

• Expect deals after the rush. Industry analysts expect discounting as all that new supply lands. Late 2027 and 2028 could be a good time to book a new resort on the island.

• Mind the season. Phu Quoc is busiest in the dry months. Its hotels ran above 90% occupancy in January and February 2026, but only 45.6% in May. Book winter stays early. In the wet season you will have more choice and lower prices, along with more rain.

Bali: location and opening date first

Bali has around 62,000 hotel rooms, according to Colliers, and about 1,700 more are due between late 2026 and 2029, all of them five-star. Most of that new luxury supply is going into Ubud and Canggu, with more planned around Jimbaran, Uluwatu and Nusa Penida.

That is good news if you want a high-end stay. Colliers expects average room rates of about US$149–151 this year, and new five-star hotels often have to work hard on price to win guests from established neighbours. But location matters more on Bali than on most islands. Traffic between the south and Ubud can eat half a day, so pick your area for what you want to do, then pick the hotel.

Check the opening date carefully, too. If a hotel is due to open just before your trip, it may still be fixing teething problems, and a delay can leave you rebooking at the last minute in peak season.

A short booking checklist

Before you confirm each stop, run through these:

1. Flexible rate or not? Pay a little more for free cancellation on anything more than a month away, especially new hotels.

2. Airport transfer. Ask the hotel what a transfer costs and how long it takes. On Phu Quoc and Bali, that can change which hotel makes sense.

3. The real opening date. For new hotels, look for recent guest photos, social posts or a reply from the hotel confirming it is open and fully operating.

4. Reviews after the first month. Early reviews are often generous. Wait for a few weeks of reviews before booking a new property at full price.

5. Event calendar. Check festivals, public holidays and big events at every stop, not just the first.

Plan around those, and the hotels on your Thailand, Vietnam and Bali loop will feel like part of the trip rather than a scramble.
