Disney takes advantage of every single opportunity to mine data from its customers. Drives me crazy, really, and often feels like an invasion of privacy. Such marketing data is extremely valuable -- and they take every chance they can get to squeeze it out of you for free.
Booking a room recently, they asked for the birthdates (not just the ages) of the twin boys going with us. I said, "You must be crazy. We don't tell anyone the boys' birthday. Way too much information for strangers to have." I gave them the ages only. And, I get so tired of being asked every time I book a room reservation, "When was your last visit?" and "How many times have you been here before?" And, what other hotel insists on having the home address of every guest in the party? I never give them everyone's address, but they certainly try for it. I'ved totally lost patience with this.
I've also gotten the old, "we can't proceed until I put something in the computer field." So, the last time they asked "When was your last visit?", I replied, "You can put down that my last visit was in 1876."
Enough already.
