Even if there is no discount with AAA, I know if the car breaks down on me in the middle of the road, I know I just call AAA and they will be there to help me. Also if you accidentally locked yourself out, they will come to help open the door.
Also, I get a monthly or every other month magazine on travel/vacation. For March/April, they are featuring the state of Hawaii. I think this is the best part of being a member. I get to see what AAA is featuring that month. Some months is Disney month and some months is Universal month and some months is all about cruising.
Being a member also gets you a book on where to lodge and dining. They rate them for you.. best or average or poor. You can also have any maps you want. I have some maps of Florida. They will also print out for you a map of how to get from your house to Disney if you're driving or to where ever you want to go in the US. It will tell you the route and how long the drive would be from one point to another.
They have so many brochures and booklets that you can keep. I have the Disney booklet and
Disney Cruise Line booklet. I also have the Universal Studio booklet. They have booklets on other cruise line too. They tell me how much I will save, when and what resort.
You can save some $$ if you buy your park tickets there too. As far as what ticket they sell may depend on where you live. Here we have Six Flags, King's Island, Michigan Adventure, Cedar Point and Universal. They were selling the park hoppers too, but I am not sure now cause the ticket is now MYW.
It pays to be a member of AAA.
