That's a tough age - they're too old for some things and too young for others! Still, here are some suggestions:
One idea would be the surfing lessons at Typhoon Lagoon, but that is expensive ($125) and you have to be a strong swimmer - perhaps not everyone would be able to join in. The Family Magic Tour of the Magic Kingdom is a 2 hour tour where you follow clues through each land. It's $25 plus tax and MK admission and is offered 2x daily.
If that seems too tame for this group, what about creating a scavenger hunt geared toward them? I'd pick one specific park or area (such as Boardwalk or DTD) and have teams with a list of things to do or find - like a picture of a hidden mickey, an unbroken waffle cone, a CM name tag, logo napkin or paper cup from a specific spot. This would work best if each team had a Polaroid or digital camera, so that you could have them do things that just involved taking their pictures or finding things they could get for free. (Remember to insist they ask for things first - we don't want to promote inadvertent theft!

) You could even do an all picture hunt, so that all the results would just be pics; then they wouldn't have to carry too much. For that one, maybe the boys could have a saying or team slogan to spell out using letters from signs or rides - posing to highlight the specific letter they need. Or give each team a character (or have them choose) and see which team can get the most pictures of that character in any form - topiary, stuffed animal, T-shirt, store window, etc. Set a time limit and have a final meeting place, perhaps at a restaurant to enjoy a meal and share results. You could give out medals or pins as rewards, maybe give extra points for most creative or funniest. There are so many ways you could do this with a little advance planning. I think this would keep them moving, get them noticing their surroundings (maybe finding things they didn't know about) and give them a chance to be a little creative.
Congratulations to the team - good for them for making it into the tournament!
