There's a mildly dubious but highly expressive phrase in idiomatic English - "All fur coat and no knickers". The saying indicates style over substance, an impressive superficial appearance without the basics to support it - and I've never known it apply so accurately to a cruise as it does to our mini-cruise on Anthem of the Seas last week.
First, some disclaimers. I've never sailed with RCL before, so can't compare it with other RCL cruises; my experience is mainly Princess, and P&O, Cunard, Celebrity and Azamara. Also, it was a very short (3 day) cruise on a very new ship, so some aspects may well change for longer cruises, and as the crew get more used to the ship.
Let's take the high points first - and some of them were very high points indeed:
Cabin was ok, with one big negative from my wife's point of view. The cabin door opens outward, and there is no space in which to stand while getting dressed which isn't visible from the doorway. So she tended to change in the bathroom to be on the safe side. Did this not occur to anyone when they designed the layout?
