Activities for non-Disney Dads who Don't Drink

Our family-and-friends cruising party includes at least 2 dads who are not exactly Disney die-hards. These awesome guys gamely agreed to take their families on the cruise, and I know they'll enjoy spending time with friends, tasting the delicious food, and taking in the beautiful views. In addition to just seeing the wives and kids having fun, lol! :D

But I'd love to be able to suggest some activities that the guys will genuinely enjoy for their own sake. Neither of these dads drinks alcohol, so hanging out at the bar won't have much appeal. Do you know of other activities that guys tend to enjoy? (Feel free to think along the lines of stereotypical 'male' things! Indeed, please stereotype!)

Should I encourage them to see the evening stage shows even if they don't care much about Disney? Maybe go on excursions at our stops? And what should they do when onboard the ship?

The ship is the Disney Fantasy, stopping at Castaway Cay and Lookout Cay.

Thanks ever so much!
