Can you bring a fold up chair to use while waiting in line, then leave outside before going in?

there really isn't enough space for that. The length of the house has an elevated part of the sidewalk that people would sit and rest. We waited in line for almost two hours.

I would say yes but the line does move pretty fast you will not have to wait long. There is also benches inside as well as some tables outside you can ask to sit on

There is not a designated place for something like that. You do go in in groups so you may have a chance to get it back to your car before you go in as the line moves.

I say yes only problem is that it might b gone when you get outside lol
