The crazy part about the band that scares me is how much you are tracked because of it. After getting back we noticed we had Photo Pass photos, you know the photos after you get off the ride you used to buy. Now these photos are all digital and online, normally requiring you to tap your band at the end of the ride. Well they were just loaded onto our account, we never even scanned our bands for these rides or anything.
At the resorts you can buy a refillable mug, or you are given one on the dining plan. This refillable mug has an RFID chip in them, same with the paper cups. You must place your mug/cup on the sensor below your drink option in order for it to be read and dispense your drink. You can only get so much dispensed in a certain amount of time, or it will just stop dispensing. I also believe they had or used to have a limit per day on refills, I never hit it.
Not to mention their "free" Wi-Fi that they highly promote. I'm curious what all is going on behind the scene and how much is being used. Because they obviously now are tracking what I drink, where I stay, how much money I spend, where I am in the park, what rides I go on, etc.
