If I'm only going to visit Thailand for 1 wknd as a vacation better off going to Bangkok or Pattaya or Phuket or somewhere else?
i guess if you like to be in a big city stay in bangkok. they also have better night clubs and stuff compared to elsewhere so if you are only interested in night life go there
if you want to chill on beach, see some nice views etc you should come to phuket
both have the obvious services and stuff
can't say anything about pattaya since i havent been there and havent heard anything good about it
