We usually do our summer trips in June, or just before July. This year we get there the first week of August for 12 days. Not sure I'm really looking forward to it - the crowds sound like they might be even busier than in June. The trick is to just accept the fact it will be really crowded and really hot, and plan plenty of midday breaks and relaxing dinners.
I am a little worried about what FP+ will be doing to our usually techniques to enjoying ourselves in peak crowds - hopefully we'll still get to do some of our favorites. I just refuse to wait 2 hours in a line for anything at my age, so if that's the only way I'm going to get on a ride like TSMM or Soarin', I'm just skipping it and probably won't be back anytime soon.
