People who value their time like it when they don't have to hassle with routing around for the credit card just buy some drinks and popcorn, and when they don't have to mess around with paper admission tickets and fast pass tickets. Sure, some folks will plan a vacation just to use the MagicBand tech, maybe only in the hundreds or thousands, but almost any marketing move would be expected to draw in some customers. And more importantly, guests who participate in the program will probably be more likely to return.
Honestly, the only people I could ever see planning a trip that will cost thousands of dollars in order to wear a Disney tracking bracelet would be the most OCD of Pixie Dust addicts (the ones who live on the DIS ... and think Lou Mongello is a god ... and have never experienced anything -- even a bowel movement -- at WDW that was less than MAGICal). ... People are not going to be planning trips over this. They just aren't.
Well . . . all I can say is that DLR treats various types of special guests very well and they do know how to send special little items in the mail.
Well ... as I've often said in the past DLR and WDW may be related, but sometimes you'd never know it.
