There isn't a lot to worry about with the EEH. Mostly we just go on any ride that is open. Even with short waits, you can only ride so many rides.
People who are in the queue before the park closes (reg hours) are able to ride, so at the start of the hours you can expect to see inflated wait times for popular attractions like 7D. Most of them, except maybe 7D, clear out fairly quickly, but don't be surprised to see long/inflated wait times for the first 20minutes.
The other thing to know about is the Boarding Group drop at 6pm, but TRON doesn't have BG anymore, just Tiana's in MK and GoG in Epcot. (And for the holidays, Meeting Santa in DS!)
One last thing to maybe know is that for 7D and Rat specifically, there will be a small rush of people entering those queues JUST at the very end of the night. For the lower wait, get to your last ride 10-15minutes before the end of the night. The difference isn't huge, just something to know if you are getting tired.
OH! I should also add a small warning that the weather doesn't always cooperate. The upgrade cost to be at a deluxe resort can be substantial for something that is a bit risky. If you are staying at your hotel for the hotel, then the extra hours are a nice bonus when everything comes together. On the other hand, if you would otherwise be just as happy at a less expensive hotel, that is also a good choice.
