I have 2 resale contracts with the same use year, and only one member number. Disney originally gave me 2 member numbers, they did not catch that I already had a member number when entering the 2nd resale info into their system. I caught it and talked with them, and they fixed it , no problem. FYI, I thought I had all my bases covered for just getting one member number - I notified my resale company, the title company, had both contracts titled exactly the same way, and still ended up with 2 member numbers. I just closed on a third resale contract with the same use year, and wondering if Disney will catch this one???
