I have been what I call - EXTREMELY - lucky and have gotten PS's at CRT the past two times I've tried. So I would be willing to make a call if needed. For some reason I have no problems getting through and getting a table. They could accomodate a larger group - maybe up to 16 I would say in one area. They have an area next to where we sat in December that is like part booth and part chairs (one side is "booth seats" and then across from you on the other side of the table is chairs). That could accomodate a larger number and be the best place that I would think they would seat you. There are some "balcony" type areas, meaning they are up a step or two from the main seating area that they also could put a group I would imagine.
So if needed, I'd be happy to make the call for you all. Someone would just need to give me their info - name, where staying, when arriving, when leaving, and phone number. Oh...and date!
