Just got back today from a two week trip. Crowds were light when we arrived on 6/20 and increased starting last weekend as expected for the July 4th crowd. But I think crowds were still very manageable.
Using refresh, we were still able to get FP's for TT, Soarin, and FEA at Epcot on most days, and NRJ at AK on 7/4. We were also able to modify our FP times without much issue. We were at Hollywood Studios on 7/3 and decided to do standby for TSM. Sign said 80 minute wait but ended up being about 45 mins.
But like one of the PP's said, the heat was brutal.
