We got a great deal on our room at Pop over Christmas.
And I believe you can also get the discount on your mom's room, it she is staying at the same resort, I think service members can book up to 3 rooms on the discount, and it is certainly better than AAA.
What have you done about tickets? Have you checked out the new Military Salute Tickets, we saved a fortune buying those. They are either 4 day hopper for $138, 4 day plus waterpark and DisneyQuest for $138 or 4 day hopper with waterpark and DisneyQuest for $165. You can purchase up to 6 per service member.
I thought they expired 14 days after first use, but the young man that activated them for us at the TTC ticket window said no, they don't expire and handed me a brochure that also says they don't, so we have a 1 day park hopper left for each of us which might make for a quick cheapy trip in the spring.
