I would not use the word "free". I would ask about a "complimentary" upgrade. We have only stayed at a cabin in Ft. wilderness and at the Swan. We got upgraded at the Swan automatically, because we are SPG Gold members, and at the cabins, we got the exact loop that I requested on my reservation. There is really not any "upgrade" at the cabins. Now, when we went to DLR, we stayed at Paradise Pier resort, and asked about an upgrade, but the hotel was full, so we couldn't get upgraded even if we were willing to pay for it. Good luck and have a great trip!
