If I wanted to add on to my contract and did it through resale, how do you know if you are getting an add-on vs another master contract? If you buy through Disney, is it automatically an add-on? If my home resort is OKW and I do an add-on, can it be for any resort or does switching resorts make it a new master? I think I know the answers to some of this, but I'm so unsure- any help is appreciated. Thank you.
