I agree with those on this thread who don't want to have to go through the hassle of being asked to verify your information everytime you call (they verify zip, last name, first name, address, and e-mail address usually when I call). BTW, I have corrected my e-mail address with them EVERY time I call, and the next time I call, it is never corrected.
Anyways, I am one of those kinds of people who if I don't like the answer I get from the first CM, I hang up and try again. I am not sure if their records indicate when I last called, what I wanted to check on or anything like that, but I get a little nervous asking the same question to a 3rd cast member, because if they do see that I just called 2 previous times, they will know I am calling to see if they will tell me something the previous 2 CM's wouldn't. Then I imagine they will become suspicious of me.
I am all for marketing information and trying to send offers to the appropriate people, but I have yet to see anything. I don't mind giving any of this information when I am ready to put something on hold. I don' t know why asking for the information up front would help them in many ways...I usually ask for rates in a huge variety of hotels and different price ranges. Quite frankly, their money would have been better spent offering a toll free ressie number. This way, they can ask all the questions they want of me at least on THEIR dime.
