Yes we go for lunch at least once a week and have not had a problem
Yes, usually there is a group of us and even if you are only going to the restaurant the parking is validated as you leave. We have never had an issue.
Yes. I do not know if they would charge more, but my husband and I had two room keys so either of us could get in the parking gate at any point, so I don't see why they would charge more. There are TONS of parking spots. Even on a sold out weekend, the parking lot had plenty of room.
