Pattaya is quite well known for being a seedy place. It is full of old white men (sex tourists? Or probably loved the place so much they didn't want to leave?) Arm in arm with local Thai girls, some of them nearly 20 years younger!
Nevertheless, it is a good place to chill out and just enjoy the beach.
There are numerous resorts along the beach and tourist spots too.
Only went there for a day trip to get out of the Bangkok. Was it worth it? For the experience, yes.
