The only SCs I really despise is ATL A (both of them), RDU (a SkyCloset even with the "expansion", hard time finding a seat on a Mon), and JFK T4 (Huge but its hard to find a seat in the afternoon and food options are typically gone). I may be biased, but my favriote club is here in MCO. It's big and isn't too crowded in the afternoon even with the VS J Pax. It was recently refurbished with new carpet and furniture and they do a good job with replenishing food, and the staff is great (never had a problem).
