You know, there's probably a good reason the Hard Rock was available on a Friday night 3 days before Christmas eve!! I'm guessing most professional entertainers know something MPIX doesn't. IMO if history has proven that big crowds were to be had at similar times in the past then the place would have been booked long ago. There's nothing scheduled until the following Friday (the long New Years' weekend) and then there's something Sat, Sun, Mon, Tues.
