Sorry, but I don't think any beach in the US is like MB, when it comes to the activities you've listed. Florida's Gulf Coast has white sandy beaches & water that looks like bath water compared to the water at MB. The Atlantic Coast beaches have sand & water similar to MB, until you get far south. In Miami, South Beach, is lively but not really family friendly. It's a different type of entertainment than MB provides. We do have beaches with activites, but not on the same scale as what your used to. If we're going to the beach for more than a couple nights, we go to MB too.
