I always do a ton of research before I go on a trip and after traveling as much as I have, I have a pretty good idea of what I like and don't like. Therefore, I'm rarely disappointed in a vacation spot. I dislike vacation spots that are an artificial environment like Vegas or the whole cruise ship scene so I avoid those whereas I love anything historical or nature based so that's what I concentrate on and I always have a good time.
However, the one time that I was completely disappointed was when we went to Bali. We were there for a liveaboard dive trip to Komodo. The dive trip was unbelievable, amazing, off the charts. Bali itself - not so much. We went right after the nightclub bombings in 2002 that killed a bunch of tourists. The tourist trade had practically dried up and the locals were pretty desperate. We were hounded and chased constantly by vendors. We could not get them to stop grabbing at us trying to sell us stuff. In addition, everyone wanted you to bargain for everything. They set prices ridiculously high, then expected you to bargain them down, but I hate bargaining and when I was hungry the last thing on earth that I wanted to do was bargain for the price of my meal. The island was spectacularly beautiful, but unbelievably dirty - mounds of trash piled everywhere. I'm sure others have had better experiences there, but it was one of my least favorite places ever.
