We have the regular dining plan and have been here for 9 nights. We had no problem sharing meals at Le Celier, the Contemporary (the one at the top, can't think of the name of it at the moment) Japan. We had an odd 1 credit that we tried to use at Tutto today because we were pretty full from eating our way around the world and we needed the remaining 4 for Jiko tonight, and they refused us and wanted to take two. We always state upfront that we would like to share and that we tip as if two had full meals. We usually order an app as well and pay out of pocket. They were not nice about it so we picked up our stuff and left. Very strange that every other place had no issues. Just be forewarned, you may want to ask before sitting at Tutto or other places. But again had no problem at all at every other place.
In my case, my DSis and I were there in March--we had an ADR for 8:45. When we checked in the restaurant was over half empty. I asked for a booth--"Absolutely not" I was informed "those are for larger parties". OK, whatever....THEN we were given a table that had us sitting on the aisle, at an intersection, where we couldn't even chat due to the congestion and traffic near that table. I asked the server if we could move and he eventually brought the "seater" who said no. So I got up, went to the desk and when the seater saw I intended to make my request to the manager, a table miraculously appeared in a less congested area. I just didn't understand what the power struggle was all about given the low occupancy of the restaurant.
