In 2017 the Thai New Year (also called Songkran) falls at virtually the same time as the Easter Holiday.
This will be an incredibly busy time in all of the major Thai cities, and especially the beach resorts. This is probably the most important holiday of the year for many Thai people, and those living overseas make a special effort to return to be with their relatives. Of course it is also in high demand for Europeans to enjoy the delights of the country. Then you have the huge number of expats living in the region (for example Singapore and Hong Kong) who will all head for the beach resorts such as Samui, Krabi and Phuket.
It is essential you book early for this period, as realistically hotels are expected to be 100% full and will usually request a minimum stay of 5/6 nights. Regional flights will also show high demand, with fares increasing as seat availability dries up.
Songkran is known as the water festival and the younger and/or more exuberant Thai’s love dousing each other with water.
This started as a small cup but now it can be by the bucket full or fully loaded water pistol. Overseas travellers who might be curiously observing the proceedings are not exempt and are expected to enjoy a good drenching with grace and humour.
Following the sad death of the King of Thailand in October 2016 the celebrations in April 2017 may be slightly more muted than usual. They might take on a more spiritual and traditional theme, which to many might be even more enjoyable.
