I have read that you can access deck 13 from the concierge sun deck. Can you enter the concierge sun deck from deck 13 or only from the lounge? Can you access the concierge rooms from deck 12 or only if you come off the from forward elevators to the 12th floor? I cannot find pictures or video that show an entrance to the concierge hallway. Just trying to get a feel of the layout. The deck plans confuse me. EDIT - I have another concierge question that I would not have thought about if not for the thread on Light Cards. I asked a question there, but so far, no answer, so I thought I'd add it to this thread. I googled light cards since we have not been on a Dream class ship and found THIS great link. I have read that magnets cannot be used on the concierge doors, but will this work in the concierge rooms? I assume that light switch is on a wall, so are all the walls magnetic?
