We stayed there in 2005, I just can't remember if you could park a 2nd car for a fee..... did you call them & ask. It seemed to me they had a overflow parking for a fee somewhere....but I could be totally wrong about this. The only reason I'm kinda remembering a conversation with them, was when we came we had 7 of us & they asked how many cars we were coming with....we only had one.....a HUGE van...lol
Good luck, but I'd start by calling the motel & asking them about it.
