yeah they even allow cats (on leashes as well, of course).
Yes on leash.
Yes, you can take your dog as long as he or she are on a leash.
Yes, no problems with dogs on a leash, at least that was the case when using our RV overnight last April.
I'm not too sure. I didn't see any signs saying that you couldn't. The museum/gift shop in the building is very fragile. So, I'm not sure.
