We are here now. So far we did DHS on Friday and AK today. Those were the parks with MEMH and we are trying to do the parks early and get out before it gets too crowded and hot. So far it is a good plan and we haven't noticed the crowds being too large (compared to other times visiting during July/August. The long waits so far have only been about an hour, but those were later in the afternoon when the crowds had picked up some. By that time we had already done most things and were getting ready to head out. Most everything we rode we had either fastpasses or had to wait about 25 minutes at the most in standby. TSM got pretty crowded and fastpasses were already about 5:00 by 9:30. But we were there at ropedrop and got our fastpasses, rode it in standby, and then rode again with the fastpasses.
We are trying to avoid the parks that are historically crowded on certain days, and don't plan to go to the ones that have EEMH, so either we have been lucky so far and the plan has worked, or the crowds are somewhat smaller. One CM yesterday told us that early in the week at DHS most people go to the right towards ToT and RnR until they learn how hard it is to get on TSM and then later in the week they head there first.
