I used to work for AAA. There' isn't a specific percentage but AAA has a block of rooms at the AAA rates for each hotel. Once they are booked up, they aren't available anymore. The discount isn't real significant but it's better than nothing. You can get it with a package or room only. If you book a package with AAA, you get a few little perks (preferred parking spots, free photo with frame, free sea raycer, free mini golf, free luggage tags, etc) and you get a decent discount with Hertz for car rentals.
