Ok, we've only been to Disney World twice so can't compare "old" Disney with "new" Disney and not sure if my opinion will count for much, but last year we really like Fastpass+. Apprehensive at first about being "locked" into a schedule but it worked really well for us as knowing we got a favourite ride booked meant we could do other things without worrying about how much of a queue there would be when we got to that ride. We also used the Disney app to change a couple of rides and didn't book a table restaurant everyday so had some spontaneity there. We had a great time and looking forward to 2018 ( fingers crossed)
