HARASW~ you've never been to Mickey's in August? There is only one weather report for the entire month. HOT. That is not to be taken lightly, STINKING HOT might be more accurate. If you can, wake early, do rope drop and ride before the sun is intolerable. Leave and come back in the evening.
We always vacation in August due to ball.....regular season....playoffs...allstars....tournaments.... but I hear July is not much better.
The lines get really long late in the day, but first thing....none at all, and you can snatch up fastpasses for a little later. I have photos of the "wait" times for a variety of rides Tower of Terror, 5 minutes, Space Mountain 5min, Test Track, 3 min.........etc. We did Test Track twice, with no wait and not adding anyone else to our cars... and photos of Magic Kingdom EMPTY, even at Dumbo and Peter Pan.
