Tori rented a bike on the island during our last cruise and had a great time. It's a lovely low cost way to enjoy the island without shelling out the cash for an expensive shore excursion. I thought I would share a few pictures from her day at Castaway Cay (I was sick back in the cabin 
). The rental cost $10.75 for an hour, I'm not sure how long she rode for but she was gone all morning and got back to the Ship to check in on me about 1pm.
