There really is no point in people on here arguing about full, limited etc capacity because NO ONE here, no one at Touring Plans, no one that is willing to share information has that information. Never has, never will.
Also Disney can say they "limit capacity or reservations" while still being at full capacity for the parks current situation. With attractions closed, restaurants limiting entry, no parade etc .... capacity becomes a very fluid number.
I was there in July, capacity was obviously being limited and everything was flowing well. I was just there first week of November, and it felt like any other year pre-covid. Lines were long and the same old wait times, very difficult to get dining reservations, QS were very busy and snack lines were long. Walkways were packed and a chore to negotiate. The only thing without long lines were the shops and that was likely because everyone was in line elsewhere. I would venture that while less people than normal, it was likely closer to the capacity of the things that were open. Even parking lots looked like pre-Covid.
I imagine it is even worse now, getting worse closer to holidays and this was a good move. No need to add more to a pool where reservations are limited or closed.
