I'm guessing you will be among the walk-up diners? This new system has everyone worried that their preferred way of dining will be a big mess. I'm in the fixed dining camp, where enough of us complained about eliminating it that Princess gave in and restored it. I suspect the DMW reservations people are worried about their new rules as well. In the past, the overflow walk-in people would be redirected to any empty tables in the fixed MDR. I saw it all the time. In any case, I don't see how this new system could be any worse than the zoo of reservation people lined up with the walk-ups in queues that went on forever. It was a nightmare and put us off Princess for the past year. I'm waiting to see how it all shakes out, and I guess you are, too.
