The recently renovated children's museum in Portsmouth is fantastic and our 3 wild and crazy guys can be entertained there for at least 2 hours (a feat rarely accomplished elsewhere). In fact, we bought a membership which has come in quite handy this winter.
As you can probably imagine the train room is Will's favorite, especially when he can stick his head in the dome to watch the choo choos over his head!
The kids also love the projection room. We give dance party a whole new meaning!
