I've visit 4/5 times this year drop me a line and I'll recommend some cheap good hotels..
it really is a great place to visit and don't get into the western propergander -given by robin cook and the like...
The people are friendly and the pagoda's are wonderful. The place is easy to get around and rich in natural resources and was the "Singapore" of 50's.
you'll enjoy it - only check out the visa -requirements as visitor are expect to change money on arrival - if you go on a buisness visa then you don't.
