Is there a place to park cars while on the trips? If so, is there a fee?

Nope there is no fee but like somebody else mentioned you park at your own risk. Remember it's not the safest place to leave your car though.

No there isn't, but be careful i got robbed there

No not a fee, but it is at your own risk.

No there isn't a fee

There is a parking lot. I don't think there is a charge to keep it parked.
