Last year it was "no booze" allowed to be brought aboard, but reasonable amounts of soda or water were okay.
Earlier this year they changed the policy to say no personal beverages were allowed, including non-alcoholic drinks.
A few weeks back I looked and they had gone back to banning alcohol only. Soda and water were apparently fine once again.
I looked this morning and, voila, the policy again bans ALL personal beverages.
What is it with Royal Caribbean? Do they have a company goal to revise policies on a routine basis? I can almost see a room full of policy wonks staring at laptops, when suddenly one of them says "Hey, it's been almost a month since we changed the beverage policy! Let's change it back to the previous revision to mess with people's minds."
I need to start taking screenshots of these to keep up with them.
