Do they have rooms that join another room?

Yes, 2 king size bed per room

Yes they do, you need to request them, there are only a few in every building. But it is a great opportunity to go with a big group and stay together.

I believe they do, but I've never had one. They are probably limited. You will want to call and ensure they have them for the dates you are requesting.

Yes they do. Not all of them

You can call and request it.

Yes they do, just ask that you be connected. We stayed in some.

Yes
