and loved it. Yes, crowds are larger now for the 50th, but the park should be relatively less crowded than other times of year. When we went in early 2005, the weather was in the high 60's, low 70's (capris and short sleeves) and wait times were 10 minutes max on FL rides.
We were in the park Wednesday, Thursday, and Friday. By midday Friday there was a marked increase in crowds. With that said, I would arrive Thursday pm and be in the park FIRST THING Friday morning. It is not a EE day, so you should make it through FL rides pretty easily, and the park should remain reasonable through lunch time. Then you can use a EE (if you have one) one Saturday, to help lessen the blow of those crowds.
We also planned our trip so that IASW would be open again.
Have a great time!
