Seconding the question. I'm wondering if you can enter the lounge on either level. I suspect we're going to want to spend a lot of time on the concierge sun deck on 13, so I was tempted to go with deck 13. But my (mostly joking) nightmare is if the entrance to the concierge lounge is only on level 12 so we have to go down the stairs to get to the lounge entrance, then right back up the stairs to the sun deck. Doubt we'll know until the first people get on the cruise, unless Disney releases some more video or other details about the layout.
