Royal Caribbean change age of of drinking

I wrote a blog last week about how I thought Royal Caribbean was perfect for families with small children or adults on their own but were sadly lacking for the 17-21yr old age bracket.
This is because at the age of seventeen the average British teenager is far too old for the kids clubs but won't be allowed to drink on any of Royal Caribbeans cruise ships until they turn 21, (you can read the full article here).

Now I'm not claiming responsibility for their policy change, I'm just saying it's a bit of a coincidence it happens a week after I write about it.

Hmmmmm, yes I know, I've got a big head! 

Problem with Royal Caribbean cruises?

You may or may not remember me mentioning before that one of the things I like to do after I've booked a cruise for someone is to give them a call when they get back from said cruise just to make sure they've had a good time and that nothing went wrong.
It's also useful in finding out what the different cruise lines are up to onboard and which lines are best recommended to different people.
I was making one of these calls today when my passenger highlighted what he thought was a major flaw with Royal Caribbean.
But what do you think..........?
