Wow, Jackie H., sounds like our itinerary is similar to yours!
We will be staying at PBH at Universal on Sept. 1, then moving to WL for six days following. I hope the FOTL access at US/IOA doesn't spoil us too much!
Since we live here in FL, the heat won't really bother us, but we both need to take a break in the middle of the day. That's why we chose a resort that seems very UN-Floridian for our mid-day rest (WL). It will be nice to escape the sun and heat for a relaxing couple of hours at the hotel during the day. I think AKL would be much the same way! We'll be trying that resort in November. I can't wait!!
So you think EPCOT on Labor Day would be the best choice? We were going to finish up any activities we wanted to do at US/IOA since we are passholders, then check in to the WL around 3-ish. But EPCOT would be great for the evening. I love the parks at night!!!
Here's hoping we have long, fun-filled days; short, quick-moving lines; and all the magic we can stand for our WDW adventures!!
