with a credit card. I waited about a week to ten days for our package to come from Disney BUT before that called member services and they were able to give me my member # and I was able to make a reservation before I filled out all my paperwork. Got my paperwork, notorized and fed-exed it back, about a week later got a letter saying our financing was approved. We made our $500 deposit on April 5th and are set to close on August 2nd, with a September use year.
HTH
BTW we didnt go the route of buying 150 points and then purchasing another 150 to get the "free" 100 points, I just wanted to purchase the whole 300 altogether and be done with it, regardless we plan on visiting Disney often regardless of the free one time 100 points, just my opinion. good luck
