Reggae Baby Cruise to Dunn's River Falls

[theotherchad]

I seem to rememeber reading a positive review of the Reggae Baby Cruise Boat to Dunn's River Falls, and we're planning on doing this excursion through RCL, but has anyone done this excursion within the last few months? Is is fun? Anything I should be aware of to get the most out of it? Are there any extra costs tacked on?

Any info? Any caveats?
