This is is weird Our check out was on the 28th and the front desk gave us day pass to use the buffet and bar till our shuttle came to pick us up, which we did. It was good till' 3pm. No extra charge.
We checked out on 1/3 at 10:00 and hung out til 3:00 with no wristbands. We had the checkout slip (small piece of paper) that you give the doorman when you leave but nobody asked to see it.
