We went last year. Same feelings as
@GymDad9.9 described. It was okay. Nothing extraordinary, but not bad. Ran pretty smoothly. Leo was a nice touch.
The only negative was that we were in a 6pm session on Sunday. Left there around 9:30, got home around 1am on a school day. But what can you do, someone has to be in that last session, right?

We did enjoyed the trip to NYC very much. We stayed at Skyline hotel, walking distance from the venue, and not too far from the Times square, but not right in the middle of the craziness. We got there on Saturday, so had some time to explore the city, and even went to a Broadway show on Sunday before the meet (got discounted tickets too).
Overall it was a positive experience for us.
