Funny, I like the discounts and all, but mainly we like AAA's roadside service. We get the AAA plus with 100 miles free towing. As our cars age (we have a '93 and a '99), AAA become an even better deal. I'd hate to be broken down (or even locked out) without my cellphone and my AAA.
The discounts are just gravy. The AAA discount on 2 nights at AKL this coming April have saved more than the cost of membership (even for the plus option).
