At this site MM, you must take a ski lift to gain access to the mountain. For those with fear of heights..... Ski lift thru the jungle at heights of 70 feet minimum.
Book outside
DCL and you will likely have a better experience.
The bobsled is memorable and unforgettable.
Of course the first run you are conservative and use the brakes.
The second run,... not so much.
They also have awesome ziplines for newbies. They run thru the forest canopy.
1st time there my 6 y/o and I linked cars. 1st run, brake applied periodically to access track.
2nd run no brake, all the way down. Oh my. My DD is .....
IRRC the front car has brake control. IOW I had no control. MY DD is a nutcase.
Or she just wanted to scare the daylights out of daddy.
Needless to say she succeeded.
Even on a DCL excursion you may buy extra tickets for the bobsled at the top.
My suggestion is book a private tour in advance.
Or, book private at pier for 1/2 the price.
All drivers within pier are vetted and licensed.
Bear right and negotiate on the way out of port. . IMO.
These folks/drivers are also known by the locals and operators of MM, DRF, etc.
This is good and helpful.
They will "work you in" to properties.
We have had wonderful experiences in Falmouth traveling to MM, DRF, BH, etc.
Of course traveling in a cruise sponsored excursion will be a herded crowed experience.
It may also limit you time and choices at said locale. You also have no say in the vehicle chosen for transport.
Research.
Good Luck
Jamaica is beautiful and rocks. Don't miss it IMO.
The locals are wonderful.
Don't believe all the fake news. (oops, sorry, couldn't resist)
Enjoy
