Can you park a semi there?

no , theres no access for semis. plus you would be at your own risk parking down the hill.no guarantee your rig would still be there.the ten minute walk is all up hill also.

No you wont be able to pass the main gate with a semi. You could park your semi at the red lobster down the hill. Big parking lot n its about a 10 min or less walk.

I actually don't know I haven't seen any semi in the parking lot

you will have to call customer service for that
