Secret tip.....The cloud 9 spa has fabulously large tiled showers, large sinks, lockers, towels and hairdryers for use by everyone onboard.
I used them all week and let my wife have the bathroom to herself. I felt like a king. She thought I was nuts until I showed her the pics.
The forward elevators go directly to the spa..deck 12. I could be there in 2 minutes even though my room was on deck 3..
We booked a spa suite on our May cruise to enjoy that area more.
