Thanks for the review!
A problem with the older ships being upgraded is they have to work with the existing space, hence the small diamond lounge.
You ought to try Oasis or Allure sometime. The Liberty Of The Seas had the clam shell shower doors when I was last aboard. Someone told me RCI was removing them and going to curtains on all showers, fleetwide. Not sure if it is true. Seems like it require a lot of work on each shower.
