I hosted my panel at the Fairmont last year. I loved the room, it was HUGE (and I filled almost the entire space)! However, is Panel Ops still at the Marriott? That was the big hassle for me; my boyfriend and I stayed at the Fairmont (called while on the stairs up to Ops to check in, dratted stairwells and no reception), so I had to scurry over to the Marriott to check in, then scurry back to the Fairmont to set up and get ready. I was still able to make it with time to spare, but it was a colossal hassle. =\
