We financed through Disney, and really weren't in the place to pay for the whole thing at once, and the downpayment was easy to come up with. We were on the 10-year payment plan for our original loan when I decided to add on more points, which we bought four years into our payment plan. The second loan was for seven years.
This year I discovered that I could take out a loan through work at a lower interest rate and pay it off through payroll deductions. Technically our original Disney-financed loans are paid off, but we'll be completely done paying off the new loan by the end of 2008, two years ahead of schedule. Now it's just maintenance fees and annual dues, which I hope don't astronomically increase over time!
