Ahhh so you seen Hua Hin, yes is nice beach there, there's some waterparks there you can checkout next time too if you're into that. Vananava and Santorini are their names.
Pattaya beach, hmmmm, of all beaches in Thailand that is one of the less liked ones, but if you take a ferry boat like 30min you can get to a small island off the coast of Pattaya called Koh Larn, it's a nice little calm getaway from Pattaya and clean nice better beach than Pattaya beach. just letting you know in case interested for next time
So you were really on the move nonstop while you where, going places for just few hours and for lunch etc, GOOD man, you must have realized you can sleep/rest when you get back home hehe
