I think it works for everyone....it certainly levels the playing field for everyone. As a "super user" of the old system, sometimes pulling 5 or 6 FP in the morning and returning in the evening with a handful, I was worried about the new system.
I used it last May,and I have to say, the kiosks and the app are so much easier and less stressful than running all over the place trying to figure out the next best thing to pull a FP for, according to what time it was, or how long the window was etc. It was AWESOME to hit one park in the morning, and hop to another, and have FP+ in the second park. When we hopped before, we knew we weren't riding headliners in the second park. All different now with a little planning. Rope drop is still Rope Drop, the single best weapon you have. Add FP+ and you've got it made.
Upcoming trip in March, Im sure it will be busy, but we have our plans in place, FP+ picked, and all ready to go. No stress being felt on our end. We love the new system, and will continue to sing its praises.
