The tour desk will have lots of options to choose from.
If you go to the Sports Hut there is a guy there that will take you fishing in his boat. I don't know the price.
I'm not sure what you mean by a buggy ride or on-air tour. There is a commuter flight that flies between CN and Montego Bay Airport and you could take that as opposed to taking the shuttle to or from the airport. Also, there aren't any safari rides in Jamaica. There are trips to water falls, Appleton Rum Tour, Pelican Bar, river rafting and things like that.
