To be fair, it's made pretty clear that they're not fully booked, they are massively over booked because their booking system got fucked up in the storm.
I agree on S3, a low point for the show, but I thought both 4 and 5 were a return to form. The letterboxing and change in music in S5 threw me at first, but apart from that I thought it was a solid ending. Sad to hear others didn't enjoy it, I got so invested that I feel weirdly part of it.
