I am fine with rides like TSMM and Matterhorn having FP. Also Peter Pan, if the logistics can be worked out. From what I understand, the lines for those rides have always been pretty long. Theme park guests expect the FP option to be available for high-demand rides. (Although, Universal takes an interesting opposite approach to HP rides.)
What I don't want to see at DL/DCA is what has happened at WDW. Not just the prebooking, which I dislike because (1) we're early birds and the old system benefited us, especially at Epcot & DHS and (2) I could never predict what my kids felt up to riding 60 days in advance. I am talking about the FP on every ride -- like Winnie the Pooh, Pirates, Small World, etc. When that happens, guests aren't just using FP to avoid the longest lines. They are creating fully regimented days, with no room for spontaneity. I will confess that we're going to get a
DAS for the first time because of my son's diagnoses; however, I also want to us and all families to be able to wander through the lower demand/faster load rides without having to first book a FP or a ride on our DAS card. A balanced approach makes for a better theme park experience for all guests, IMO.
