As a teacher, and because of my daughter's sports schedule, July is the only month that works well for us.
It's not totally insane....just slightly. Not as bad as Easter Break for sure, but it is hot, and there are tour groups. You can't avoid the tour groups in the parks, but you can kind of avoid them outside of the parks. Stay at resorts that they don't frequent, and eat mostly at table service restaurants.
We manage the heat by going early in the morning, and leaving in the afternoon. We have a nice dinner, and then maybe back to a park at night.
We are fortunate to be able to go every year, so we kind of have it down to a Science.
