I got a email with a pin number in January. At the time time I did not know this was anything special. I told a friend who was going in May and she called a used it. A couple weeks later my family decided to go in June and we called and used the pin number to. Now after reading the boards I know that I should not have shared it. We both got are bills at the email pin rate. Do you guys think we are ok and slipped though the system or when I go will they say something and I have to pay rack rate. Thanks for the help.
