when i went i just turned up and found somewhere both times, tho it was 12 years ago now. if youre worried just have a look online and read a few reviews. most of the basic ones are much the same. ton sai was the cheapest with rai lay being a little bit nicer but also a bit more expensive. i think mt view resort is on rai lay east. it might have even been where i stayed first time tho looks a lot nicer now. hope you both have a good time, its awesome. the start to 1,2,3 is the best start to a route ever.
