I have to say, staying at the Poly over the Thanksgiving Holiday, I couldn't believe that it was booked solid. The only time we saw many people was at the Volcano pool-- not the quiet one, also peak times at Captain Cook's. I think the sprawling nature of the Poly has a lot to do with the uncrowded feel. Wandering around? Hardly anyone. Lines at the monorail were also not bad, we never waited for a second one in 10 days.
