Disney has changed the name from "concierge" to "club level," which better reflects the level of service.
Beach Club is the same as the others. Last time I was there you got Andes mint chocolates on your pillow. I guess they couldn't think of anything better beach-like.
The lounge is smaller than others, but close to the elevator, so if you get all ready and stop to eat a quickie breakfast before you leave, you don't have to backtrack.
The help desks were always staffed (unlike Boardwalk's) whenever I was there and they are conveniently located outside the lounge, right by the elevators.
Our room looked straight out over the back entrance, with the water and the Boardwalk after that. Sitting on the balcony, I could hear the din from the Boardwalk, but once inside I heard zip.
Like all the other Club Level rooms, you have to get your room key out to get to your group of rooms - at the Beach Club, this is done in the elevator. You have to insert the card before you can press the button.
However, I gave up on WDW "concierge" a long time ago...because it wasn't concierge service. So, I haven't stayed in those rooms for...I dunno, maybe 2 or 3 years and everything could have changed in that time.
Have a great trip!!!!
