We arrive on a Tuesday, and I was going to book MK for the Wednesday and Friday so 8 and 10 days out. I believe Wednesday might have extended evening hours at MK.Just tried the new LL process this weekend. It's a totally different strategy than before. Much preferred Genie.
In fact, because of the 7 day advance rule for staying on site, I would NOT choose MK to be my first park day of the trip again. Too many slots already taken/times left if any (7MDT was gone before I even had the chance).
Epcot and DHS are too Tier 1 heavy. DAK today was actually a perfect park day with all the selections available.
I am far enough out that I could easily change everything. Really will not know for sure until I book our dining reservations. We are still at the point that certain restaurants are a big factor. This year it will be Space 220, Ohana and HDDR that will factor into at least 3 days of which park we are at.
