Exactly.
I called our local AAA, and they were $20 more than
Undercover Tourist (not sure if the AAA price had taxes included or not).
And if you go to Mousesavers and subscribe to their newsletter (do it before the 15th of the month), it will have a discount code for
UT. With that code, my UT tickets went to $50 less than AAA.
It may be that AAA will run the same deals as Disney. UT is currently running buy 4 days, get 1 free, for example.
