Here is the thing... all that stuff also could happen with the key cards. They would randomly not open the doors, not be loaded correctly, or not allow charging when they were supposed to. So this really is not new to the MBs. Now, I am not saying the MBs are perfect or anything. Just that it seems a bit funny to me that people will say this is because of the MBs when it could always happen before. I guess since these are new it's easier to just say they have the issue?
Absolutely. In fact we had more problems with the key card once the sensors went in, than with the mbs. Charging, when we set it up, has always been hit or miss. Entering the room has been easier with the mbs than the key cards. We never had admissions on room keys before, as each time we've been there we have had APs which didn't go on the key cards before now.
Problems happen much more frequently with the MB's. It was confirmed by me on three separate trips by different cm's who were helping us deal with multiple problems with our MB's.
Not our experience, and remember that each cm has only seen the issues they have seen. Each cm ends up with their own understanding of things, and their own little set of superstitions about what to do.
We loved it because we love to go to the parks not carrying anything and with nothing in our pockets!
If you getto the parks and glitch happens to all the bands, and you have to prove to the CMs who you are....what then? If someone wants to buy alcohol and you're carded, what then? Room charge doesn't work after dinner? Someone breaks a leg and you go straight to the ER?
It's really good idea for each adult to carry ID. To carry a backup credit/debit card for payment. To carry an insurance card so there are no annoying issues should someone have a hospital-requiring accident. For those of us with access to discounts, like DVC or APs, we should carry those cards as well, to prove that weare allowed the discounts.
In short, I carry MORE now with the mb than I did before because I'm bringing it all plus the mb.
