So Pattaya in May ?

[pong]

Both-its indeed about the worst time of yr (in westerners ideas)- hot AND humid-just before the rains come and bring refreshiments. Lowest prices too-and the time when Thai kids get their ´summer´ holidays from school- for very much same reason.
Best alternative for that time of yr for Asean tropics is IMHO INdonesia-the part thats south of equator (Java, Bali). History, monuments and willing guys too-plus its all readable and the language is very easy to learn. Cheaper as Thaild-but more primitive in many respects too (lets say ´more 3d world´)
