Are you able to get out of the parking lot if you leave early?

We left right before the last song ended and got out in a timely fashion

We left a funny packed Slayer show after the last song, and still got out of the parking lot within 15 minutes. There are two parking lot entrances, and multiple exits. The folks in the town of Gilford are also great in that they shut down an entire Side Road to assist with the flow of traffic.

Definitely! We left pretty early because our little was ready to go home and it was very easy to leave.
