Podaar isn't really wrong; it's not like Universal sucks or anything, but then again, Animal Kingdom doesn't either. It's really personal taste, and you don't know until you go. Personally? I LOVE Universal; it's more a ride/adult oriented place, then you go to Margaritaville for a couple drinks, then to either Pat O'Briens for more drinks, or Emeril's for an excellent meal. I also LOVE Disney; it's more an event/kids oriented place, but not at all in a bad way, and you can go to Downtown Disney (they're calling it something else now... Riverwalk or some shit?) and pound drinks at the Irish Bar there, or go to any of about five different EXCELLENT restaurants.
Either way, you're getting your buzz on, you're not at work, you're not shoveling snow, and you're heading back to a hotel with your girlfriend so there's a >0 chance of action. I say "WIN WIN".
