Is a big rig allowed down that road? Is there enough parking?

They do have a very big lot. You can Google earth it. Seems like you would have no problem at all turning around.

Yes! Plenty of room to park our 40 ft rig with an SUV in tow. We usually park right in front of the little shack in the lot, come at it counterclockwise and face out.

I would say yes

Yes big rigs will have room

Huge parking lot
