As a grandparent you are always looking to please an active grandchild . They not only were active at GSE they had fun. They even offered extras because we were repeat customers. I would recommend them wholeheartedly for a family fun day.

The bumper boats are a must do for my family when we visit the Cape. The batting cage is a bonus for my husband to participate in. Harwichport has so much family friendly activities to offer for the whole family.
