We went for 11 days in July last year because we had no other choice due to DH work schedule. I actually dreaded it, thinking about the heat, crowds, etc....
However, we would do July again without a second thought.
1) you'll be there over value season for deluxes, so you will be getting the lowest rates and then if you have a discount on top of that,it's awesome!!!! (We had WL CL for just under $250/night!!)
2) the crowds ended up not being as bad as we imagined. We've been there during Thanksgiving week and over Thanksgiving and
never again! but, summer crowds were there but seemed fairly dispersed. Never once did we stand on a bus, or wait in line longer than 45 minutes (w/out Fpass)
3) the heat was far better than I had imagined. I hate being hot and actually the first few days, I was shocked at how bearable it was....at night, the first few nights, we were even
cool??
Later in the trip it got hotter but we utilized the pool in the middle of the day and going to the parks at night strategy.
The only negative we saw was the tour groups. Funny, I knew they would be there and thought that would be the least of my issues, but oh boy! There were many times when we would go to pick up a Fpass and two members of the group would hop in front of us and start getting Fpasses for 60+ people!!!!!!!
The return times would change by hours in a matter of seconds.
Also, we had a couple of times where we were in line and then all of a sudden we had a whole group coming through the line to meet the few group reps that were waiting up ahead.
One time a CM saw this happen to us, and pulled us in front of the group.
So, other than the tour groups, July was awesome! Dare I say, our best trip ever!!! So no, I don't think your crazy!
