We will be going to Acadia in our travel trailer and plan to stop here for shopping. As we have a baby, if we need to, can we count on staying overnight in the parking lot here?

It's possible to park overnight across the road, behind first perish church. There are limited spaces available for trailers. Turn right coming up before arriving the store car park.

No overnight parking signs are in their parking lot

There are a few camp grounds in the area worth staying at. Wolfes Neck Farms is gorgeous.
