i made a report about this place last year and still stands, love the atmosphere!!
im staying in a backpacking bungalow on the beach, but has blasting a/c for 650 because i have my dog with me and didnt feel like running around looking for a place. also, jimbulljag was staying in a gorgeous room at the hilton and i just spunged off him for the facilities
anyways, i found that there is more nightlife than i found last year. the hilton has a disco thats pretty good, but very expensive. there are a bunch of karoke places open late 4-5am right in the center of town, can walk home.
i highly recommend hua hin, especially after finding the extra nightlife
