I'm copying this from another thread so as not to have to type it again. I was there Monday through yesterday. Every park was, by my definition, insane. I have greater than 10 WDW trips and 5 DLR trips, so I am not a novice to this. Even Spaceship Earth was 60 minute standby! It was crazy. We tried to park hop and it was over 90 minutes wasted in waiting on the buses and then getting through security/entrance lines at the next park. There was no option to swim at the resort since the temps were in the 30s-50s all week. Water parks were closed down due to cold temperatures, so anyone who would have been dispersed to those parks was now most likely in one of the other parks, making the crowds there even worse! We did not cut our vacation short, but it was not the experience we were hoping for. I expected high crowds, and planned for them, but this was insane and not enjoyable. I did not feel that Disney responded well to the exceedingly high crowds, especially in regards to the buses.
Here is my other response:
We just got back tonight from our first (and last) trip over spring break. We typically pull the kids out at a non-holiday time in May but we added a few park days onto a short
Disney cruise, so there we were. The crowds were so much worse than I ever expected. I'm sure someone will say "a crowded day at Disney is better than being at work" but I can't agree with that. I don't want to be using time off from work, spending this much money, to be herded and pushed around for 3 days.
Yes, we rope dropped, booked FP, tried to book 4th FPs on the app, had dining reservations, had a touring plan, etc. We did all the big rides we could with FP. There was very little 4th FP availability, as expected. Lines were awful (though FP lines moved quickly). I did not ride standby for much, as SB waits were over 150-180 minutes for SM, RNR and other headliners for hours each day. Even "lesser rides" like Spaceship Earth were 60+ minutes Standby. The places we really noticed the lines the most were at the buses at park close. We stayed at AKL, and buses literally came 30 minutes apart at night to the parks. It was made worse by the unpredicted cold snap that left many without clothes for the weather. We waited almost one hour last night for a bus from DHS to AKL. The temps were in the 40s! We had some warm clothes from the cruise, but many others didn't even have a long sleeved shirt or pants. Miserable. We will Uber next time, but I don't like feeling I'm being "forced" to spend money on Uber when transportation is one of the perks of staying onsite. I realize there can't be a bus to each resort every 5 minutes, but at park close, they should put every bus on a route to get people moved in less than one hour.
We still had a good time, but this is our one and only spring break trip. We have been numerous times and never felt like this. I felt buses were being diverted to the upgraded park to park transport service, so there were less buses on the regular routes. Bathrooms in all parks were dirty, and at least 30% of paper towel holders were empty ( this was at all 4 parks and was a noticeable change that I had never experienced). I'm used to seeing someone cleaning those bathrooms nearly all day long, and I rarely saw a CM in any bathroom. CMs overall were great, and AKL and their CM were superb. We did a VIP tour day with a plaid, and it was the saving grace of the trip. We met some other great park guests and had some pixie dust from another guest pin trading. We passed on some pixie dust by giving our paper fantasmic FPs from our lunch package to a family that had been in the hotel for the prior 4 days with the stomach flu!
Planning is going to help anyone going at a busy time, but I feel that even with the utmost planning, I do not enjoy this level of crowds. Everyone has their own threshold, and I met mine this week.

I'm getting in that line, that's a pretty short wait to me, there's even time for a churro too!! 
I guess Einstein had it right, it's all relative.
