But wearing a robe in the main dining rooms isn't against the "rules". The only dress code
DCL has is "no swimwear or tank tops for dinner". Nothing about PJs, robes, shorts, ripped jeans, tutus, whatever anyone wants to wear.
I'm not defending the right to wear a robe to dinner, just pointing out it's not prohibited.
Is it "bad taste"? I think so. Do people exhibit bad taste? Yes.
I find it puzzling that the whole cruise vibe (or "feel", if you will) is being systematically eliminated. Anyone ever watch a movie or TV show that takes place on a ship? Shared tables (heaven forbid, you mean I have to eat with strangers?!), tipping (I already pay enough for the cruise, why should I tip?), dressing for dinner (It's my vacation, I'll dress as I like), wearing life jackets to muster (who cares if I take the jacket off before returning to my room, if someone trips on the straps, it's on them). All those things were the norm. Sadly, it seems, cruising is not the experience it used to be.
