Obviously, everyone's tax situation is different. You need to contact your preparer.
But...
In general, the interest is decuctable. A good way to finance is with a second mortgage on your home. The interest rate will be lower and it is obviously deductable. A loan from Disney is also going to be a real estate mortgage loan and will also be deductable. The portion of your dues that goes for the real estate taxes is also deductable. You get a statement telling you how much property tax you have paid with your dues.
Again, their are all kinds of restrictions, income limitations, number of homes you own, all these variables need to be addressed by your tax professional.
