Ok, so I am new to cruising but confused about the deck plans.
I was told Deck 9 had no connecting staterooms. Connecting staterooms are shown with an arrow symbol between cabins, as drawn in the middle of the cabin.
Looking at Deck 9, I see no arrow (which makes sense because they say no rooms connect on Deck 9), but what does the teeny little square represent between each room by the balcony? Does it mean anything? Maybe an air conditioning unit?
