Husband and I went 2 years ago, and are headed back to Florida this Saturday for a week of Disney, IAAPA, and Free Play Florida. I've been looking on the IAAPA website and can't seem to locate anything about the cheaper Thurs/Fri passes, so though I'd check to see if anyone knows anything about it.
We'll be at IAAPA on Thurs and possibly Friday morning, then Free Play on Fri evening only since we've got to hit the road very early Sat morning for a 10 hour drive back home in time to feed the dogs. Who else is going to either event?
