I should have said this earlier but did not think of it. It be a good idea to bring your bikes. I am sure many will do the island tours (there is more than one island) The islands are not all that big and one of them does not allow vehicles at all and for the ones that do it is not fun to drive one of these big ole trucks around.
All of them rent bikes and or golf carts to get around. Most folks from the area take their bikes.
We automatically take ours when we do island hopping and I guess that is why I did not think of it.
