We went last weekend and had a blast! It all depends on how much you do when you're there and if you get you monies worth.
Granted, we deliberately picked opening weekend to avoid the chaos but we had a lovely time. And three and under get in free so we took my three year old and two of her friends.
We got hot chocolate, watched the ice skaters, wandered thru the decorated atrium, rode the train....met the Grinch.
They had an awesome time and we will definitely go back next year.
The parking is expensive though so carpool if you can
