This is the closest hotel I could find
DanSai Resort Hotel
089-277-1251
Theres nothing fancy about this place but it he closest one to the festival, last time we stayed 35 Klms away, this is a popular event and that is why I went today and Looked for hotel rooms today if yuo want to go and want to stay in Dan Sai, I stongly recommend you book hotels now.
Fan rooms are 750, air con 1K per night.
The lady is going to want a deposit so you will probably have to do a bank transfer. But, you will need to work that out with her. She does not speak english so you need a Thai Speaker.

If you guys haven't been to this before it is one heck of a lot of fun, enough so that this the second time for me in as many years. Should be more fun this time we don't have to ride 35 Klms back to the room. Heck I might even have a beer and I don't even drink.
Remeber I said it was not a fancy hotel but it's clean and comfortable and close.
