What do you think about single cabins?

I know this is a family travel site and we worry more about cabins that can hold families, but what do you think? Seems like the cruise lines are going after the single travelers. To be honest, having to pay double on many cruises and tours really does not seem fair. Single travelers have gotten the shaft for a long time, and I think it is only fair that someone has finally started to listen. Norwegian Cruise Lines was the first single cabin at sea where there was not a single supplement, and they seem to be doing well. Below is an article that appeared in USA Today recently, about Royal Caribbean also jumping into the single cruiser mix. So what do you think?

Is Royal Caribbean looking at adding cabins for solo travelers to ships?That's the word today from UK-based TTG Live, which says Royal Caribbean president and CEO Adam Goldstein discussed the possibility this week on a preview cruise for international travel agents on the line's new Allure of the Seas.
Goldstein reportedly said the line is considering retro-fitting several older vessels with singles cabins.
"We probably won't make any big changes to our two new biggest ships (Allure and one-year-old sister Oasis of the Seas), but we recognize that there is a demand for the single traveler business," TTG Live quotes Goldstein as saying. "We are going to be revitalizing our older ships such as Radiance of the Seas and Grandeur of the Seas, and so we will have opportunity to create spaces for single travelers then. It is definitely something that we are looking at."

Single cabins have become a relative rarity in the cruise business, where the business model revolves around cabins designed for two or more people (click HERE for a comprehensive photo tour of Royal Caribbean cabin categories, as seen on the new Allure of the Seas). But at least one other cruise company, Norwegian Cruise Line, is moving into the market for single travelers in a big way.
Norwegian's new Norwegian Epic, unveiled in July, has more than 100 cabins for singles, and the line's CEO already has said the company plans to offer more solo cabins on two vessels it recently ordered for delivery in 2013 and 2014.
