Hi, I just booked the Poly for Dec 3rd-7th. I have never booked so last minute and have no idea or time to find out things going on. I did see the Christmas party is on then so I booked that. Is this free dining or a crowded time? I dread if its free dining as I see I won't be getting into any of the popular restaurants that I may like. What are the chances for walk ups if needed? Anything else I need to know? Thanks!
