Probably not much help to you but we were recently on the Volendam and the Loft/Oasis was an incredible space -- we all wished we were young enough to go in!! Way up top where it was private, South Seas motif c/w hammocks, waterfall & pool with colored lights at night. And lots of cool indoor stuff -- an arcade type room with big overstuffed sofas, etc etc. I was very impressed - and envious.
