I hope e-nights are in effect in May when Piglet203 and I go. The early entry mornings don't really affect us as much as e-nights do. I have never,in the eight times I have been to WDW, done an e-night. I'm extremely looking forward to doing this. I think it will be a lot of fun. If not, we will have a great time nonetheless. I don't see why they would have them around Thanksgiving and not when we go (May 25- June 5) so I think things are looking positive for us.
Despite the disapearence of EE, I think E-Nights will stay around because you pay money to get in (to pay for the rides and the CM's). Plus, it isn't every week, only 2-12 times a month.
I put this on the Theme Parks board, at RADP they're saying Disney had the MK open late those two nights, then changed the hours to close early and added E-night. There is also a rumor that Disney is reopening hotel rooms.
