According to Royal Caribbean CEO Adam Goldstein, Royal Caribbean will begin adding cabins for single cruisers to some of its older ships.

"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.”

For those looking to get a single cabin on a newer ship, such as Allure of the Seas or Oasis of the Seas, you're going to have to keep waiting as Goldstein mentioned these and other newer Royal Caribbean ships will not receive this update.

So why the change? Royal Caribbean is considering adding single cabins because of the increased demand from people who travel alone. Most ships are designed with cabins for 2 or more people; single travelers have to pay a single more if they want to go on a cruise.
