Usability 
The American Automobile Association (AAA) mobile site is a useful one to bookmark for US residents and visitors alike whether they are driving or not. Most services do not require an AAA membership to use.
The best part of AAA Mobile is the "TourBook" which provides online mobile access to the hotel, restaurant, event and attractions listings in the AAA's print guidebooks. The AAA guides are quite comprehensive, easily rivaling commercial guides like Fodors. Listings include descriptions, address, click to call phone numbers and the AAA's "Diamonds" quality rankings.
The site also has driving directions, click to call access to the AAA's members-only roadside assistance program and listings of discounts on goods and services available to AAA members.
I was a little disapointed by the driving directions modeule. The directions themselves are fine and offer a choice of one to a page, turn by turn directions or with all steps together on a single page. What bothered me was the clumsy user interface for entering start and end points. It's overly complicated and fussy with multiple fields on separate pages for street address and city,state or zip code. In my experience, a design with single free form fields as used by Google Local, Mapquest and Live Search is much more efficient and intuitive
