Crazynuts, your making us all jealous! Comanche 250, nice airplane!
Some airports in the Bahamas close early, I think in Eluertah, just call ahead to make plans if your delayed. If going to Freeport, enjoy the our lucaya resort, I think they have a choice of about 15 restaurants and local shopping nearby. Try the casinos as well, I love to go gambling there.
In Nassau the beach is nice at the british colonial? I've also done some awesome parasailing and snorkling is a great choice of destressing and just enjoying the water, salt and sand.
Have fun!
