The are a ton of locations that are built simply for lounges that few people even know about spread all around Epcot. Almost every country has one and all pavilions in Future World have one. Is it hurting you that there's ONE Lounge location for members who pay a decent amount to Disney every year and it's put in a space that's otherwise not being used other than for storage? Sure, that used to be a guest area, but Disney isn't going to put the money into making it that again (if they ever do) until they refurbish the ride. The lounge will go away when the attraction gets a refurb, but unfortunately, that's not in the cards right now.
Simply put, the joke is getting old.
