I heard that the princesses have moved to Ariel's in DCA and the Plaza Inn is Going to be Minnie and Friends - at least that is what I was told when I made PS arrangements for the end of Nov-beginning of Dec.
Yep, the Minnie's Mistletoe Buffet at the Plaza Inn inside DL is taking PS calls now. I know because we just made our PS arrangments for our trip during Thanksgiving. $22/adult and $12/kids. Wendy, our CM at Disney Dining, said that it is a buffet with Minnie and four friends (no Princesses) from the Park's opening until 11:00 am daily.
