I'm going to be in Bangkok for a few days and then have a few more days before I fly to Chiang Mai. I was thinking that I would go to either Kanchanaburi or Pattaya because it's relatively close to Bangkok. Which should I go to? I really want to see Erawan Falls but have heard that it's really crowded (especially in November?). Pattaya sounds nice because I wouldn't mind hanging out on the beach but then I've read some negative reviews of this place. Is the beach really that dirty? Is the ocean really too gross to swim in? Which of these two locations do you prefer? And why? Thanks!!
