The lounge is on the 6th floor, with a stairs to the 5th near the lounge entrance. Concierge guests will most often be assigned to those upper floors. I had a bunk bed room on the 6th floor (above Storytellers) with a view of the pools and DCA, classified as a Concierge Theme Park View. The lounge looks into the Brisa Courtyard, so the nearest concierge rooms will also look into the courtyard.
You have 3 requirements (bunk beds, lounge proximity, view), so make it clear to the CM when checking in which are most important
