My MIL is buying 210 points at OKW and we're looking at a big family trip next year at a grand villa. We were looking at a 7 night stay, but now they want to do a 10 night which we won't be able to do. So if we leave after 7 days can we still all get the dining plan with our tickets or does everyone need to have the exact same thing? She called Disney and when she mentioned "DVC resale" they clammed up and gave no help. Has anyone tried to use the dining plan in this way?
