Excursion Questions - Jamaica and Mexico

[JTlikestheDuck]

We've booked the Adventure Falls and River Tubing excursion in Jamaica next week, is it worthwhile to do? Also, how is the drive to get there? My family tends to get car sick and twisty mountain roads will not be good. What are your thoughts on the All-Inclusive Isla Pasión by Power Catamaran in Mexico? We've never left the ship while in port in Mexico or Jamaica since the kids were young but now they are 9 & 12 so wanted to do something different. We're sailing on the Treasure and figured there would be a lot to explore just on the ship so not sure about excursions.
