We love Ocean City, NJ. We have stayed in hotels and have rented houses. The Beach Club Suites are right on the boardwalk and have a pool - nothing fancy, but water to swim in. The location is great, and Ocean City is a family friendly town. The boardwalk is great for shopping, riding bikes, and entertaining the kids with rides, arcades and a water park. THe beach is nice too.
There is a Beach Club Hotel too, but the rooms are a bit smaller than the Suites. The Hotel pool is right on the boardwalk/beach but the Suites pool is on the second floor.
Ocean City, NJ was voted one of the top beaches in the US by the Travel Channel.
