Contrasting calls on Royal Caribbean sailing
Nellie's Beach is somewhat similar. Columbus Cove, the largest of the three beaches and the most distant from the ship, is a good spot for families. It has a collection of inflatable floating slides and rafts offshore as well as the Dragon's Splash waterslide, a twisty, low-slung, blue metal slide that must look like it's worth every penny of its $27.50 daily cost to kids of a certain age, if not their parents.
One could easily make a day of it at Columbus Cove alone. There is a cafe, bars, restrooms, a trading post, beach chairs and a station for the island tram.
There is also a free one-way shuttle boat from the pier.
The tram operates on a sand road that forms the spine of the island and really makes it easier to get around, especially for guests who are older, have young kids or are not very mobile. I walked the length of the place to see it but was happy to hop the tram to go back.
One of the most pleasant parts of Labadee is that there's lots of shade provided by mature Australian pines, coconut palms and other trees. The walk from the ship along the pier was hot on a late October morning, but the rest of it was pretty breezy.
The ocean side of Labadee is protected by a reef, so the waves broke rather gently on shore when I was there. A promontory point anchors the crescent curve that at the far end becomes Adrenaline Beach, where there is a breakwater and daybed-style cabanas.
