Interest on your loan from Disney is generally deductible. That is a federal tax thing not a state tax thing and states just follow the fed on that one. There are exceptions, among which are: (a) if you own another vacation home, you usually can deduct only 1; (b) if you have some other kind of loan which is not secured by your interest in the property, it may not be deductible; that can happen with resales and some get a personal loan from a timeshare lender that is not secured by the property.
