Yes but as a once a year resort guest, I am the main beneficiary of FP+. It is a big benefit to me to be able to book FOP, Everest and Safari at AK and wait in line (even if inflated) at Navi, Kali and dinosaur. There’s no way you will convince me that I would wait less time to ride those 6 rides if there was no FP+ vs having it. It’s just simply not true. There are only 2-3 headline rides and to be able to cut the lines saves a massive amount of time b everyone wants to be on them (MMRR, MFSR, SDD, etc).
Same for Epcot. Same for Hollywood. Same for MK (but maybe saves least amount of time b there are more rides)
