Stop in for a cup of coffee
Just booked an overnight stay at a local hotel in Ocean City NJ for my wife and daughter plus one of my daughter's friends. It's been sort of a tradition over the past few years to do this so my daughter can take one of her friends to the beach for 2 days. It's usually one of her friends that wouldn't get a chance to go to the beach over the Summer otherwise. Sometimes it includes the other Mom too and I just book a room big enough to accommodate all.
Ocean City is a good choice because it is a family oriented beach town with a boardwalk and no clubs or alcohol sales so the beach party crowd stays away.
