Not that I remember seeing. We've been pretty close to the railing every time (thanks to this thread, I'm sure!) and I don't remember seeing PP photographers there. Anyone else??
Re: people standing in front of the tables by the railing as others have been discussing... yes, they do! We sit at the table to eat, and then most people seem to approach the railing during the castle show and wishes. We've gone back to the table to eat some more between the two as well. I do remember one time when some plates were cleared before we were done, but we just went back for some more.
It's really been a great experience every time -- looking forward to it again in Sept!!
