I had A LOT of fun when I've visited Gainesville. But, seriously, Gainesville isn't exactly known for their clubs. Purple Porpoise? The Grog? (or however it's spelled...don't remember since I was drunk) These aren't as classy or renowed as Roxy, Tabu, or Antigua in Orlando. But, I don't think clubbing is exactly the best option for the first meet up. I'm all for a nice lunch somewhere.
My vote is still for Orlando!
