Hua Hin
Nice place to visit for a few days, walking the beach is a nice past time, with plenty of places to get a lounge chair and relax with a brew, or have a bite to eat. Nicer beachs at the south end of the City, with less rocks or none at all. Plenty of Hotels and guest houses to stay at.
Bar scenes near the Hilton and to the north of there, as well as Soi 88. Cheap bus system to go to Cha Am for a day trip, or south to Pran Buri and other smaller places.
Just go and enjoy yourselves.
