I don't know about AARP, but AAA does give shipboard credit sometimes otherwise no discount. I think that is the way most travel agents are now, not much of a discount, but shipboard credit instead. At least that is what I have found. I recently booked a cruise for Dec. 2007 and AAA had a deal where I got $150 shipboard credit, but I know that promotion has ended. You may want to contact your AAA agent to see if they have any deals right now.
