I will likely draw some ire here, but I’m going to go ahead and suggest that you really focus first on what WDW doesn’t have. Many will point out that many of the rides are slightly different and need to be experienced on both coasts. For sure I was glad to experience each of them, but if you have to choose between Peter Pan and Mr. Toad, I’m going to go with a resounding MR. TOAD. Hopefully, with rope dropping you won’t have to choose between anything.
We went for four days in June 2018 and Pixar Pier was still closed and WOC was dark and there were still some things we couldn’t do. BUT - we also opted for five rides on GOTG and four on RSR and three on Alice, etc. We loved the novel rides and were glad to reride them.
I found the rest of Carsland to be in the one-and-done category.
Fantasmic is different than at HS, but it was much better to my family. Even though there isn’t amphitheater seating, we loved it. The action takes place so much closer
I’m sure you’ll read this else where, but start trying to see the fireworks from the first night on. Because of Santa Ana winds they are frequently canceled, so have fireworks as plan A every night until you get to see them.
@lolabear_la @Wahoohokie and @Jeff_AZ are all pros IMO. I’m sure they will weigh in.
