"Although FP+ was not as bad as I had expected, I did find that our family left the park earlier in the afternoon because we had already used our FP and the sb lines were too long or because we scheduled out FP for evening and sb was too long." There are plenty of attractions and activities to fill time in the parks even when busy, mid day and top rides have long waits. I was able to fill time from 2p to 8p last Monday with plenty of things to do in MK without a FP+ to use. Also visiting during lower crowd periods still allows for many more rides throughout the day without need for FP+.
I have traveled many times during spring break and fall break do I know all about low and peak crowds time.
"Even though you are supposed to have flexibility to change you FP choices, the app is not always working and the popular rides are already booked."
This is true "I feel that in order to ride all that we want rd is even more important than with FP-. " Has been a fact at WDW for several years, the advantage of RD to ride the most popular attractions, including repeatedly
We are and have always been rope drop people. Yet this time it was more important than ever because for example you are now unable to pull a FP for TSMM and RnR or for Soarin' and test track so rope drop is very important. I know these are not MK rides but there is a chance that when mine train opens MK could take this tiering system too
"I also saw more stressed out parents and children." Also been the case in the parks for some time, not all is related to FP+
When a parent is cursing at their phone and loud ing complaining about the app in the middle of the parks, I think that it is a pretty good assumption that is has something to do with FP+.
" You could see that some were stressed because they were unable to get the app to work properly, some because sb lines were longer, some because of the crowds in general." Park has been busy in last month due to spring break, one of the busiest times of the year, been that way for years.
"Lastly, you see so many people with their noses stuck in their phones that they are missing out on the magic all around them." Seen that in the park and other public places for last few years, again I doubt it has little to do with FP+, many are going to be on their phones anyways and still missing the magic (which is their choice)
