How do they do it? How do eleven kids, two parents, and a cat named Zsa-Zsa manage to hang out together on a small island for an entire summer? Who knows?

And no vacation is complete without a haunted house, a gorgeous movie star, a seashell salesman, a ghost from the sea, and a disappearing baby brother. No Rosso vacation, that is!
