Could someone explain the logistics of the AAA discount to me? Wife and I and 2 kids are going in May. We're also taking grandma to help babysit part of the time. Grandma's husband is a AAA member, but he's not going. Several questions: (1) can we use grandma's husband's AAA discount even though he's not going but grandma is? (2) if using the AAA discount, is it okay to go through a "disney specialist" travel agent or are there advantages to going through AAA directly? (3) if we need to go through AAA directly, what are the logistics on that? Thanks.
