I enjoyed the tournament very much, but I do have a few points:
Size of the terrain: some terrain pieces are huge by T9A standards. It might be that I have been pampered by playing with the 2d terrain, but in some cases the tables were cluttered with terrain (my first table had like 8 or 9 impassable terrains) or had a couple of very big terrain pieces. Not a huge deal, but definitely room for improvement.
Price of the food: the food was expensive. It was good and tasty and well prepared I have to give you that, but expensive for the portion that you get. Most tournaments have food included.
Otherwise, I had great fun and I will definitely come back again.
