I received two of the code emails this week. I booked my trip this morning and was speaking to the castmember about the codes. He didn't really know why some people get them and some don't, but he thinks their marketing dept. may choose a group of people based upon where their last name falls in the alphabet. I know that I've received one from an email I used to get the usual Disney DVD, and I've recently applied for the Disney credit card and I think that might have something to do with it too.
