The Savoy is Perfect and gets my vote. If we are going to do South Beach we might as well be on South Beach. This is a nice resort.
The beacon doesnt have a pool or beach, you have to walk to the public beach (ok, ok, its across the street, still I prefer a private beach area)
The others are on Collins and you can’t see the Ocean or Beach (or the Bikinis) and have to walk two blocks to reach Ocean Blvd where the action is.
