We've stayed CL at all resorts except YC and I remember the same. Two things that really impressed me about WL and BWI. In both cases, when the lounge is closed, there is somewhere to sit. At WL, it used to be a huge area overlooking the lake and the lobby, but it sounds like that is changing. At BWI, it's that small seating area in the hall outside the lounge. But at both BWI and WL, the CMs have been so friendly, offered to get anything we needed during the lounge closures, and sounded like they really meant it. They brought cookies, milk, juice boxes, etc to our youngest not only upon request but when they saw him looking in. CMs at both have happily brought out wine and beer, soda, etc.
And at BWI, I don't remember ever being kicked out of the lounge for the 4-5pm if we were already sitting there. I've seen it closed if we approached during those times (with corresponding offers to get something for us.) But nobody has asked us to leave the room during the switch over from afternoon snacks to evening appetizers.
The vibe at BC CL, however, is far different from our experience at BWI and at WL. Particularly disappointing to me, because I so love BC otherwise.
