We are staying at Saratoga Springs using my wife's Aunts DVC points. We have another couple who is flying in and staying with us and wanted to use DME. For some reason to setup DME for Saratoga Springs they need my wifes aunts DVC Member number. We have the reservation number but they wont accept that. Does that seem correct? They seem to be making this a big hassle and are very unfriendly to our friends who are flying in. Anyone have any luck using DME and someone elses DVC?
