Royal Caribbean guarantee cabins: what you control

Two beds or one? Check the cabin layout before you book
Need separate beds? More space alone doesn't confirm the layout. Check what the listing for your exact ship, category and sailing says, and confirm what it leaves out.

On Radiance of the Seas, the Junior Suite advertises 120 more square feet of interior space than an Ocean View Balcony, a larger balcony and a tub. What that changes for two adults, and what to check for your cabin.
