Simple, crowded, super attractive for an European, more choices (beaches) where to spend a day, beautiful beaches, good food (if you consider so fried corn or pancakes with whatever you wish), relaxed people, relaxed atmosphere, warm sea...it is about 20 minutes far from Pattaya port by ferry.
It'll cost you 20 THB (0.60 Euro) to get there. Then you have more choices where to spend a day, right at the port beach, or choose one of the four other attractive beaches. Taking the TukTuk, a small open bus/van, will cost you almost nothing. Bargain, bargain, bargain. Golden rule of Thai vacation!
If you are looking for just a little bit spoiled paradise, this is the one! Here you can admire the smile of simple people offering you in front of your eyes made snack, juice, or if you look for a cheap beer and you are not too much into luxury, this could be a good choice.
Do not forget to try fried insect at the heart-warming market when you'll be waiting after fantastic day for a ferry back to Pattaya.
I think to myself, what a wonderful world! Ouuu...yeee.
