After about 50 stays I gave up on the JW a couple of years ago for several reasons--but one the primary reasons was the boring repetitious lounge offerings night after night. If it was sliders night you knew exactly what you were going to get--sliders, quesadillas, broccoli w/cheese sauce; same with Chinese night and Japanese night over and over. Maybe they have changed, but it was enough to drive me away.
I've been staying since 2011 and the nights were so predictable! But there might be hope! On a visit last month there was a BBQ night with steak and they were making an evening cocktail which was tasty. I don't recall either of these before but I didn't get a quesadilla night which was my fave!
