True, but since FP is not set up in advance you have to take that more into consideration because if you don't and make your selections for MK and forget that you have an ADR for and Epcot Restaurant on the same day it becomes a problem.
Yes, it did happen that way before, but, since you weren't doing the FP setup 60 or 30 days out, it was a little easier to just go to the one park that had the ADR and not make a mistake and set yourself up for two parks in one day. It's a minor difference, but, one that needs to be pointed out to avoid a costly mistake at the most or a major disappointment at the least.
MM+ = My Magic+ the new system with Magic Bands and advance setups for everything, probably including bathroom visits.
