In some of the summaries I've read of the movie, they say that the Housemans are Jewish, and Kellerman's is a resort for Jewish families. Well, I'm not Jewish, so... how could reviewers tell? I admittedly don't know lots about the faith, but as far as I've been able to tell, I don't see anything alluding to that.
This just may be the dumbest question I've ever asked here. But I'm just curious.
