We did the party cruise to the Falls in Ocho Rios and we had a blast. If I were going back I would look into the river rafting. So hard to go wrong with either of those choices.
We also did the Stingray City tour, highly recomended. Though if you cant feed them anymore I wonder if there will be as many. After we got back we just walked over to one of the resorts and used their beach for the afternoon, no charge. I have heard that this is frowned upon now, its been 2 years. But I found this place by doing a little search.
Never been there, but seems nice.
Let us know what you decide to do and post pics. Have a great trip.
