Would not recommend going to WDW anytime in July, August, or September. Just too hot and humid, even though crowds tend to lessen as soon as the schools start. The FL heat and humidity just saps your strength, and if you are like my DW and myself, trying to see and do everything in only 5-8 days tends to add to your fatigue. From now on we are going to November, even if many attractions are down for rehab and/or refurbishment. FastPass if great. One thing I have seen done many times now is that families will have 10-20 tickets with unused days on them and go to 3 or 4 attractions in the MK and EPCOT especially and get FP for them. That way they have no waiting if they watch the FP times that are posted. IMHO that defeats the purpose of the FP, but I have to say I admire their creativeness. Whatever you do, do not try to push the override button on the FP machine. That will get you in big trouble with the CM and/or get yourself kicked out of the park.
