It is worth it for towing and other discounts. I think around where I live it runs between 40-50 for AAA.
You can get some package discounts that do include dining but you have to book those directly with an AAA agent. Room only discounts range from 10-20% depending on which resort and which season. These you can't add dining too.
When special codes come out just figure which is the better of the two and take that one, you can't stack discounts.
