hua hin

Hi again everyone
flights all booked for next year. But im going to do something diferent.
Cambodian bf is comming to Thailand for the 1st time, he has applied for a passport and is very excited.
I was thinking about showing him around BKK and then taking him on a train to Hua Hin for 5 nights.
Has anyone got any good sugestions for a nice hotel, ive looked on Agoda and there seems to be alot and very cheep too.
After HH will take him up to the river kawi and stay there for a few nights before we head back to BKK and fly to cambodia.
Will keep him well away from Patatya where i will be going on my last week of my 5 weeks holiday alone lol
thanks for any info
