Why do we call it a bank of elevators? My guess is that at one time, only banks had lifts. Rest assured, this is no bank.
Royal Caribbean ships have elevator banks that are functional, stylish and serve as a showcase for hanging art. No two banks are the same which is not only refreshing but helpful. Helpful, in that, on some of the larger ships, it's easy to get disoriented. Having distinct elevator banks helps with getting your bearings. I can't tell you how many times I forgot whether I was at the front or back of the boat. Unless you're up top or by a window, it's almost irrelevant, but knowing which direction to walk for a meal is an acquired skill.
Also, each night the crew replaces a floor tile in each elevator with the name of the day. So not only do you know which part of the ship you're on, you're reminded the day of the week. Little orientation hist never hurt anyone. Anyway, if memory serves me, this was at the back of the Oasis of the Seas, or was it the front?
