Maybe this is just ME, but outside of these boards, how many times has someone's upcoming Disney World vacation come up in a casual conversation and you ask about what ADRs they have planned or FP booking and the person looks at you like "Huh?" And when you try to explain it, their eyes sort of glaze over? Or they say something like "I don't know about that really, I think my
travel agent might be taking care of that, not sure..." I mean, I have frequently come across people who say "Disney World...is that the one in Florida or California?" I live in a major metropolitan area in the NE, where lots of families have traveled to Europe and frequent the Caribbean & Cruises, so this is not people who are inexperienced planning trips. They just aren't likely to accept a theme park trip with their little ones to be over complicated.
Or how many times have you been in the parks when people walk up to one of the hardest to get table service restaurants and seem surprised there are 0 openings for the day? Or, they walk up to BBB with their little one in tow hoping to walk in without a reservation for a make-over? Or, when there was FP+, how many times did you hear someone mumble something like "must be nice to be rich enough to be able to walk to the front of the line."
I guess my point is, the multi-tiered system that is rumored seems way to complicated for the vast majority of people I have come across IRL to be able to deal with.
