Consider this (somewhat) hypothetical example: Tom and Katie are DVC members staying at their home resort with a few family members. All have access to the DVC and deluxe resort amenities. Two other family members, Mitch and Mary, are staying at the Swan and Dolphin. Thinking that Mitch and Mary might not have the same access to Disney amenities as the rest of the family, Tom adds Mitch and Mary to their DVC room reservation (they have capacity). Are these overlapping room reservations likely to cause problems? Will Mitch and Mary have the same privileges as the rest of the family?
