Sorry unless I am missing something this rule here states that it is only open to US residents.
The sweepstakes is open only to legal residents of the United States and the District of Columbia who are 18 years of age or older. Void in the Puerto Rico. This sweepstakes is subject to all applicable laws and is void where prohibited by law. Employees of Disney Destinations, Delta Vacations, their respective parents, subsidiaries, affiliates, suppliers, advertising agencies, and their immediate family members or persons living in the same household are not eligible.
