Maybe if that stuff worked consistently, but there are an awful lot of guests that are not happy with being the "guinea pigs" for MM+ and it hasn't gone well technically or practically. The whole system is far from polished or even ready for primetime from my observation and experience. That's not just one person's opinion, either, very few CMs in multiple areas are less than enthused with how things have worked, and the consensus seems to be that the uphill battle and issues are still just beginning.
And they have spent more than they initially thought, and the budget (or rather the over-runs) hasn't stopped growing from what I understand. While yes, I'm sure the system will eventually make back its investment (or they'll put as much lipstick as they can on it), it is and has been a money pit so far.
