my children are 23, 19,17 and 9 (he just turned 9) They ALLLLLLL enjoyed the bobsledding in ocho rios.... only 5 minutes by tour bus from ship. We found it was less expensive to book the sky explorer chair lift ride to the top of mystic mountain. up there-- there is a pool, water slide, restaurant and bar included in the price of the chair lift. then at top you can purchase rides on the bobsled or zip lining. i think 5 rides on the bobsled was $40.... much cheaper than the cruise ship and also i was afraid if i pre purchased it one or 2 may chicken out. they are still talking about this excursion. grand cayman we met friends who took us to 7 mile beach --great time. i heard the sting ray thing was great but that wasn't for us. have a great time we just got back yesterday.
