Jaybrad,
Just back today from Dolphin & WDW. I am sad to say the crowds are BAD!! Park attendance is not down, every park was packed! In the late afternoon & evening there were 2 hour waits & not FP's left at many of the rides.
This schedule worked best for us. EE was terrible, it did not work for us, there were still 30-40 minute waits. Get to the park at opening or 15 minutes after opening. DH would wait in a line & I would get a Fast Pass for another ride, we would ride 2 rides, get another FP for another ride, take a snack break or find a ride with a wait of less then 35 minutes. We would leave the park around 12-1 pm & take a pool/hotel break. There were many times where we would just stand around with nothing to do because everything was so busy, it was amazing. We did do E ride night one night. For the 1st hour the waits were still 45 minutes & then the 2nd hour lines were better, we rode Splsh Mt. 2 times in a row. We will never go back in June. The heat was terrible as well, buy a Mister Fan, that helped cool the kids down a lot, we would also take water bottles & pour on the kids heads while standing in line. Also bring your rain ponchos, it rained hard 2-3 hours everday this week. Hope you have a safe trip!
