We had planned to have a kitchen sink on our trip (Aug 13=24) but never made it. We tryed to go around 4:00 one afternoon but it was a 45 mim wait. Didn't think there would be a wait so early in the day.
I think that CM is not accurate. I'm pretty sure the Kitchen Sink is specifically excluded (by name) from the Dining Plan - no matter how many credits you pool
