We were there the week before OP. There were large crowds and I can certainly see how it is not for everyone. So if OP feels like they need a break from WDW it's probably a good idea.
However that week we were able to get plenty of FP the same day, and we are a family of 4. We rode FOP once with a FP but on a different day we rode it by getting there at 7:00 am, so there are strategies if you don't have a FP.
Several times we were using our FP for things and the FP line was backed up for whatever reason. At that point they were clearly stating to standby guests that they were going to experience a longer wait. They let the FP line go through and held standby until the FP line was shorter. That could account for lines that don't move. But if people have FP wouldn't it make sense to give them priority? Op liked the old paper FP and the FP priority policy was the same then right? The only difference is advance planning.
One example this trip is when we rode Kali. We had FPs and the FP line was stretched very long out of the entrance. The sb line was not visible from outside and much of the standby line was empty. The posted wait time was high- longer than I would have waited. So we were in the long FP line, moving slowly, and stand by guests were walking through their line briskly. Laughing..."glad we don't have a fast pass!....I think they posted the time wrong! Fast pass is slowing them down! Ha ha!" Well, they were letting FP in and holding the standby line which was long once they got inside to the switchbacks. They stopped laughing.
At the time, FP were still available for Kali. Everyone is allowed 3 FP, included in park ticket. An accurate long wait time was posted for standby. It makes sense to me that they should let FP through to give them priority over stand by. The folks in stand by made a choice to either use their 3 FP for other attractions or refused to participate in FP. Either way it was their choice.
There were attractions with long sb times posted that we did not have FP for. We chose not to get in line at the time. I either made a plan to return when I knew sb would be short or I made a FP for later if possible. Either way- in one week we rode everything we wanted to ride, often multiple times, without waiting longer than 20 minutes at most.
When I go to parks where the only way to get a queue pass is to pay for that, then I really feel frustrated. Other than rope drop, there is no way to avoid lines, and they can be very long. So I would be very sad if Disney returned to no FPs at all.
