Well, as your appointed tourguide

, I can offer a few suggestions as to how to spend some extra time.
Busch Gardens is really a great park. They have some neat shows, too (iceskating shows in Florida--who knew?)
Kennedy Space Center is a big draw, too. I don't know how many of y'all plan on renting a car, but there are usually shuttle services offered through many of the hotels.
Ybor City is just a few minutes from the airport in Tampa. It used to be really run down and kinda scary, so the Tampa Coucil decided to clean it up and now it's a bunch of bars, restaraunts and stuff. I myself haven't been down there in a few years, but it sure was fun when I did!
I KNOW I don't have to tell all y'all about the stuff here in Orlando. We've got the Mouse, Universal, Islands of Adventure and SeaWorld.
There's plenty to do! Shoot, for the less adventurous, just stay in the hotel lounge!
Hope this helps with an itinerary. Like I said, I'd be happy to give anyone some ideas coming this way. Just let me know!
