While we've never used ME in the past, I did inquire when making our reservations about possibly using it for a one night stay at SSR this upcoming January.....long story....why we're only staying onsite for one night. MS told me I could add it closer to our dates if we decide we would like to use it. However, he made a statement which may have something to do with ME differentiating DVC luggage from cash reservations at resorts. He told me after the first of year there may be a cost associated with the ME service. Maybe by tagging DVC bags they get a better grasp of how many DVC vs. cash ressies utilize the service? Don't know, but, it would appear to me they're tracking those bags for some reason...........
