We booked this through Royal Caribbean. It was a combo tour with Dunns River Falls. The tour bus met us outside the shopping district found just outside the cruise port. The A/C'd van drove us to Mystic Mountain for a bobsled ride & lunch.
You start with a 10-15 minute chairlift ride to the top of the mountain. The bobsled ride was fun...but the line was very slow moving. Word to the wise for thrill seekers, DON'T USE THE BRAKE!!! You won't go flying off the track, but it made for a funnier ride! We rode with 2 carts strapped together since we were traveling with a 6 & 8 year old who weren't tall enough to ride by themselves.
The lunch was nothing to write home about & very limited choices. Staff was not exuding friendliness. A nice surprise was the infinity edge pool and the water slide into it! Be sure to take your swimsuit & towel!
There is a cool lookout tower at the top of the restaurant which made for some nice pictures. You finish up with a trip back down to the base via the very same chairlifts!
