I will be very bummed if this rumor and the rumor about the Cali Grill both being closed for the better part of 2013 are true (we were hoping to do a splurge trip at a Monorail resort in April of 2013 but will probably not do it if all of the Poly restaurants AND Cali Grill are closed during that time).
I realize there are still good dining options at GF and WL, but IMO, part of the fun of staying at a Monorail resort is being able to eat at least one nice dinner at each of the 4 resorts closest to the MK. If I'm going to fork out the $$$$$ to stay at a Monorail resort, I want to have the full experience.
I suppose the new Be Our Guest restaurant in MK will provide a new dining option not currently avaliable but this doesn't make up for 'Ohana, Kona and Cali Grill all being closed at the same time (and I have my doubts that it will be as good as any of them, instead, probably more like a second CRT).
