We financed through Tammac in October. I believe our interest rate was 10% for 5 years. They were fine to work with, just a little slow in getting paperwork back to Disney.
We are now going to pay off our loan...we know we wouldn't finance for the whole term, but it allowed us to get a great contract before we had all the money for purchase.
Now I'm starting to feel add-on fever! I just have to convince DH!!!
Good luck!
