marcie, i know many stay onsite for that early entry.
i just came back last night and didn't have any issues with the new potter rides when i went around 11:00 and again around 2:30.
could be that it was pure luck i only had a limited wait.
never used the early entry for all 12 mornings onsite.
too early for me, as EE was at 7:00 during october.
once i entered the building for the new ride, only had about a 15-20 minute wait to get on the ride.
i was in the right place at the right time after reading about how long others had to wait.
a few times the ride was down since the wait had hit 90 minutes for it.
the TM told the group outside that they are closing the line so that all inside could finish the line before the park closed.
ride wasn't down but they did this so all would be done around park closing.
you asked about rides, TF and DE always had lines when i went by it.
when i went on them, i used the express line and the waits were very short.
you will love being able to do the parks regularly now that you live in florida.
have fun at the darkside.
