"Marigalante Pirateland vs Sunset Cruise"

Was wondering if anybody out there has gone on one of these cruises. They sound like a lot of fun. We are mainly thinking of our 18 year old son. Thanks for any info that can be provided.

Thanks for the input. I have to agree with the Marigalante Pirateland for our 18 year old.
Are the banana boat rides and snorkeling included in the price or do you have to pay extra?
