A couple who sailed six times on Royal Caribbean ships have been given the heave-ho by the company and banned from the cruise line forever. Their crime? They complained too much, according to expertcruiser.com.

When their cabin plumbing overflowed, they demanded another room. Seems reasonable. When a faulty door latch locked out the husband on the balcony for hours, the duo asked for compensation. Maybe some free cocktails. But Royal Caribbean says they went overboard with their criticisms posted online at Cruisecritic.com, a popular travel Web site.

I say the cruise line has lost its bearings. Whatever happened to the customer is always right? Even the whiny ones. Look, it should be a some RCL flack's personal challenge to please these picky customers. Why? Because there are lots of other cruise lines. Because word of mouth spreads like wildfire. Because they're the big kid in the playground and can afford to play nice.

What do you guys think? Should RCL have banned this miserable couple?
