On the Voyager and Radiance class ships, approximately mid-ship, the hull bulges out into a "hump" or "bump". There are about 10 cabins on each side of the ship on the Voyager class, and the same number on the starboard side on the Radiance class. On the port side on Radiance class are the glass elevators that look out over the sea. On the upper decks there are fewer cabins on the bump, because that's where the suites are.
Is it something you should want? Hard to say. We like them because some of the balconies on these cabins are larger than a stardard balcony.
If you can get a Royal Caribbean brochure, you can get an idea of what I'm talking about.
Serenade of the Seas b2b January 2016
Just had a bump /hump cabin on Brilliance--it was terrific--the front part of the hump-- midships--on side opp. the elevator bank. It has an oversize balcony (with lounger & 2 chairs & table) & very convenient to the sitting area outside the library--can hear the centrum music from a quiet spot, near to stairs & elevs..booked it early as they go fast It was cabin 9576..one note they parked the service cart nearby but it did not bother us at all. We also had a lazy cabin attendant but maybe they rotate them!
I truly fancy the aft balconies BUT I have been know to park it on the hump occasionally. Most of them beat the alternative and have nicer balconies but there are exceptions so be careful (like 7606 on the Radiance class ships is quite small). Being on the apex of the hump is also nice for viewing. If your cruise budget can afford a suite, we had 1556 on the "Radiance" and it was superb (okay my wife didn't like the sun being blocked by the public deck above us but otherwise it was superb ;>)
We had the aft cabins on the Explorer on deck 10. The baconies were 2-3 times larger than other balconies, the cabins were laid out with more floor space......the best yet.....the price was the same as the other balcony cabins.
The hump cabins on the voyager class are right by the elevator banks... Does anyone know if the proximity of the elevators is negative in any way? (i.e. noise from elevator itself, or increased traffic??)
