The resort also includes a waterpark with a little pirate "museum". It's basically a series of posters that outline the history of piracy. There's also a little pirate gift shop.
Sunscape Montego Bay also has a small marina with a watersports hut. For a small fee, you can ride in a glass bottom boat out to the reef (minimum 2 passengers). This is a fun thing to do. One thing to note, though, is that they do throw bread in the water to attract fish, so if that bothers you, this is probably not something you would want to participate in.
