Blue Hole & River Tubing in Jamaica - who has done this excursion through RCI?

We will be on a cruise docking in Falmouth, Jamaica next Feb. and I'm checking into excursions. Most of them we are interested in are located quite a distance from Falmouth. Although I usually book excursions on my own, I think this time I'd feel more at ease booking an excursion through the ship without having to worry about getting back to the dock on time. If anyone has done this particular tour through the ship, could you please let me know how you liked it as well as anything you didn't like. Thanks.

I have not done this excursion through RCI, but I have been to the Blue Hole and it is amazing. I would recommend everyone go before it gets over run now that the cruiselines have found out about it.

When I went it was small groups of people and when we were taken though the pools of water and waterfalls we were on our own....now it will be as overrun as Dunn River Falls.
