Anyone have tips for cheap family fun near the South Shore side of Mass? I was born and raised in Quincy, but relocated to Indy in 1995. My family is visiting in July for 2 weeks (we're staying in Marshfield) and I'm looking for some ideas for cheap family fun. We don't want to drive a great distance because it already takes us 16 hours to drive there. I'm out of the loop since I don't live there anymore and my MIL is clueless. I've got the beach already covered.
