Is it wheelchair accessible

Not really, small area, tight fit. We drove over 1 he, seen it in 10 minutes, very over priced t shirts & caps. Not worth the $10 parking

Walking area is cramped due to all the displays set up. When we visited on a Sunday it was very crowded. I paid $25 for a t-shirt and personally think that's a reasonable price. They do have cheaper items such as key chains if you're wanting a souvenir.

Yes

Very tight I am big guy in the shoulders and was rubbing and bumping things.

It's pretty cramped inside. Wife dropped me off and drove around the block so I could look around. Elbow ran into a few things and previous comment is right about the prices.

Ramp but very crowded inside an lots of people narrow aisle
