Hi Pooh,
It's so funny how two people can have exactly the opposite view. I was there from 7/28 - 8/13 (we left at 7am on 8/13 - it may have rained that day?).
It was HOT! Did I mention it was HOT, lol!
We thought it was not crowded at all. I did not do early or late entries and used FP's. But, compared to crowds I've seen before it was managable and hardly crowded. By using FP's we never waited in any line except Pirates of the Caribbean.
We also thought the weather (rain) was great. It barely rained the entire two weeks we were there. One night at the beginning of our stay (July 31) it rained in the early evening and didn't stop till we left EPCOT and went back to our room. We had a couple of other days it might have rained for a few minutes but then cleared. Most days we saw no hint of rain. Other days it looked like it could rain in the afternoon but never did. We thought it was a practically perfect two weeks as far as rain goes. We also did the beach 2 days and I swear it must have rained in Orlando the one afternoon we were at the beach. We got nothing. I think it depends on what park, where in Orlando you are, etc.
Sorry to hear it was crowded for you! What dates were you there?
