Hi there, so sorry for the delayed response. I will start by saying that it wasn't a horrible experience, just not as good as we expected, or as good as what we have had in other concierge lounges, Disney and elsewhere. Here were my major disappointments: 1) no personal welcome, check-in or offer for a welcome drink (I was really looking forward to that). We stepped off the elevator with our luggage, they checked us off of a list and said "have a great day!"...ok? 2) I was basically blown off by the staff when I inquired about safe food for my kiddo with a serious food allergy. She basically didn't eat in the lounge while we were there. Thank goodness we were only there for three nights and when we moved to WL, they were amazing with her allergy 3) the staff were "ok" but any time we asked for a beverage or even asked a question, we felt as if they were annoyed 4) I saw the chef once during evening service, for like 15 seconds 5) the lounge itself is small and feels very cramped.
I hope this helps. It wasn't so bad that I wouldn't stay there again, but it will never be my first choice. We stayed at Beach Club, CL in September and it was worlds better than YC.
