As far as how hard are the rooms to get ..... I booked two SV studios for July 3rd towards the end of January and waitlisted for concierge. I think it was less than 2 weeks that one of the waitlist rooms came through for concierge at what I consider a busy time of the year. I'm afraid I won't be as lucky with the second room so I am not sure what I am going to do, having rooms on separate floors. Still pondering that one!
