I say that because, I would assume that Disney would have specific instructions not to award anything that requires someone to be of legal age to sign or enter into contract.

1.ELIGIBILITY
Void outside the fifty (50) United States, District of Columbia, Puerto Rico, Canada, Mexico, the United Kingdom and where prohibited by law. Persons in any of the following categories are NOT eligible to participate or win prizes in the Giveaway: (a) persons who on or after May 1, 2006 were or are directors, officers or employees of Sponsor, Creata, or their respective parent, subsidiary, or affiliated companies, any other individuals or companies engaged in the administration, development, production or distribution of the Giveaway and any advertising or promotion agencies associated with the Giveaway; (b) persons who on or after May 1, 2006 were or are on-site directors, officers or employees of any commercial establishment at the Disney Properties (as hereinafter defined); and (c) persons who are immediate family members (defined as spouse, or biological, adoptive or step- mother, father, sister, brother, daughter, son or any dependent under applicable income tax law) of any person in any of the preceding categories, regardless of where they live, or who reside in the same household, whether an immediate family member or not, as any person in any of the preceding categories. Except as otherwise set forth in these Official Rules, prizes won by a person who is a minor in his or her state, province or country of residence ("Minor") may, in Sponsor's sole discretion, be awarded to his or her parent or legal guardian, and, in the case of prizes that, in Sponsor's sole discretion, require winner verification, that parent or legal guardian will be responsible for completing the verification process and executing all "Prize Claim Documents" (as hereinafter defined) and otherwise complying with all requirements imposed on winners set forth herein. Notwithstanding the foregoing, in the event a Minor is the winner of any prize in which the winner is permitted to travel to, stay at or attend an event, site or destination, such Minor and any guest (as applicable) must be accompanied by his/her parent or legal guardian on such prize and, as applicable, the parent or legal guardian will be considered one (1) of the allotted guests.
I doubt that the Dream Team has been instructed NOT to award certain prizes to underage guests, as that would violate the whole randomness of the prize process!
