Hi, It's my understanding that you can only get the dining option with the MYW package, which would include your tickets. If you book through
AAA they will only discount the room portion of your trip, usually 10-15%, (although they don't break it down for you) they will only give you a total price for your package. Check
www.mousesavers.com, that site will tell you what the AAA discount will be depending on the season that you are going.
So, you can book room only reservations through AAA and go without dining...or book the package with the dining option and your tickets will be included as well. You have the option of only buying tickets for the number days that you will visit the parks, not the number of days that you are staying at the hotel.
Hope that helps.
