I have never been to WDW (going for my first trip in 3 weeks!), but I am a DLR vet. At DLR MaxPass has been a game changer. I do what several on here have stated, I make the plan (full day), but I will be letting the FP lottery guide me after my initial 3 FPs. Then I will go into my plan on lines and check off what I have done, and optimize based on what we have already done and what we still want to do. At DLR I often get to do far more than the plan suggests I will be able to do. I understand that WDW is a very different animal and I am trying to adjust my expectations accordingly, but I think the plan and optimizing periodically will still result in a successful plan! In my notes for the day, I am also adding a “wishlist” of what I would like to do if more time is available at the end of my plan (ie: ride dumbo again). I just make sure it is not something I would be super bummed to miss, but more like a second ride on a favorite ride or a ride on something the I was on the fence about, but wouldn’t mind checking out (ie: magic carpets).
