Just a note on tax deductions.
You can probably deduct a percentage of your dues whether you pay cash, finance through Disney or finance via a home equity loan. The portion you can deduct is the property taxes, a pretty small amount.
If you finance, you may be able to deduct interest if your loan is secured by your residence. My understanding is that you cannot deduct interest if you finance through Disney, if you take out a home equity loan, you probably will be able to.
I am not an accountant nor an attorney. Tax law is convoluted and just because Bob can deduct something doesn't mean you will be able to. Talk to your own tax advisor regarding your specific situation.
