We were staying at the WLV this past NYE.
We did not go to any parks and had a great time. During the day we rode a surrey at Port Orleans Riverside and then took the ferry to Downtown Disney.
In the evening, each deluxe hotel had professional photographers (until 9 P.M.) taking free family portraits in front of each hotel's Christmas tree. They zapped the pictures onto your photopass card. We decided to make an adventure of it and see how many hotel's we could get to before 9 P.M. (we had a car) to get the photos. After 9, we continued on with our own amateur photos. It was so wacky that we had an amazing time and great, happy photos to show for it.
We ended at the Beach Club and then walked over to the Boardwalk where they had a DJ and a dance party on the front lawn. We danced for a while and then decided to head back to our hotel at 11:30 to beat the traffic. We ended the evening down at the WL beach watching the MK fireworks, which blanketed the sky. We then moseyed on back to our room and got to bed at a reasonable time for the next day without any hassle.
Whatever you decide to do, I hope you have a great time!!!!
