When we were there in June, I specifically asked about parking at the Poly for breakfast and leaving the car there and heading to the MK. I was told by the CM at the front desk of OKW that as long as we had the parking pass that they gave us in the window of the car, it would be OK. This is one of the perks of staying on property they said.
It was really great to be able to do that. It was our first time renting a car and we will do if for every trip now. It was wonderful...
OK, done babbling.
