We took the snorkeling, bike and floatation package from the Dec 1 2002 Wonder cruise. I believe it was 32.00. We were told the bike rentals were good for an hour. We were a bit longer and they didn't mind. We just parked the bikes and went back to our place on the beach.
We all left all of our belongings by our beach chairs. Nobody ever bothered any of our stuff. Cameras and wallets came with us. Check the chain for tightness on the little ones bikes. They are coaster brakes and the chains seemed to be streatched out and fell off 4 times on my 10 years olds bike.
