Precisely. If you’re worried about the walkways and bathrooms and such being a bit congested, that’s going to be the case at some point regardless of what capacity the parks are at and this isn’t the best time for you to go then. If you’re having reservations about the congestion, back out now rather than getting there and realizing you’re not comfortable. However, if you know you’ll be ok in those situations, as infrequent as they may be, then now is the best time to go.
People using the term, madhouse, to describe the parks, even people who post on Disboards is difficult to judge at this time. People saying that may not have been to the parks in a year or so and were seeing the pictures of the parks completely empty but had a few instances of congestion and broke out the madhouse word. Others may have been going regularly since reopening, enjoying the lower crowds, and the first sign they start picking up they immediately overinflate their judgement of it and call it a madhouse. Others may just want to scare others off from coming so more park reservations open up for them. You can never know.
But the moral of the story is, if looking at the pictures and reading the reports at this point make you upset and worried and all you want to do is complain about it on a message board, it probably isn’t the best idea to visit Disney right now.
