A friend and I were discussing this at break, and we were wondering how much of a PR nightmare they're going to have, after letting people make all these dining and fastpass reservations way in advance, then the people show up to the parks and the usual delays happen, causing them to miss all their pre-assigned times for everything, lol. Even IF all the stuff with the bands and the My Disney Experience website work perfectly, what if Cinderella Castle is running late and they don't get seated for lunch for an hour, and then they miss their precious afternoon fastpass+ for Space Mountain that they arranged 60 days ago? This just seems ripe for having upset guests, but I guess we'll see what happens.
