Thank you to all who answered. This was hypothetical. I received a pin code that I used for our trip in April. Since then, I have received 2 more pin codes, with dates for this year. I am hoping I will get one for next year’s hypothetical trip. Unfortunately, our April vacation in 2011 is the week before Easter. I figured that if I was sent a pin, it would probably end a week or so before Easter.
I am not sure why some people get pins, but I think it is helpful to sign up on their website, order planning DVD’s, and things like that.
