We rented a place at Bass Rocks and are looking forward to entertaining. However, we have been warned by the landlords that PARKING IS AN ISSUE! So aside from our one car, we need to find a place where guests can leave their cars and be shuttled by us. So any suggestions? Gloucester HS, Stage Fort Park, Gloucester commuter rail station? I don't mind shuttling people, but I want to avoid getting stuck in the long lines of traffic for Good Harbor Beach. Is this doable?
