Oh no, I did not mean to cause anyone to worry. I was just hoping to give a heads-up based on our experience before anyone requested a room expecting to use the stairs.
I remember the cast member I mentioned and another two in the lobby saying that the stair doors to access the guest room floors were locked from the inside. They said that guests could not exit the stairs to access upper guest room floors.
However, I would assume you could enter the stairs from the guest room floors and exit the stairs on the ground floor at any time. I felt confident that we could have exited the hotel if we needed to do so, and the lobby stairs between the first and second floor were not enclosed and seemed to be in constant use.
Additionally, there was a lot of construction still happening at
Pixar Place Hotel at the time, so I would not be surprised if policies were continually changing.
Unfortunately, we were not in a position to be able to use the stairs on that specific visit, so I did not go test the doors myself. I hope you get a chance to hear from someone who stayed recently and used the stairs. We really enjoyed our time at the hotel.
