OP will be there in June, so they'll be seeing the new version of RoL that is only just starting Memorial Day weekend. I find that when you couple the words "new" and "Disney" together, all bets are off. However, since we are talking about RoL there would have to be some major changes to turn it from "meh" to "must see". However, it is Disney and if they do manage to create something that is a "must see", word of mouth would have the RoL FP+ and packages disappearing faster and standby lines starting up sooner.
I'm sure info about the new RoL will be reported on the boards when it debuts a little over a month from now. I'm really hoping we get something that is a "must see".
