Yes, you can absolutely book five people in a single stateroom on Royal Caribbean, though availability is limited to specific cabin categories. On most ships, you will need to look for "Spacious" or "Family" staterooms, such as the Ultra Spacious Ocean View or Family Interior, which often feature a combination of a Royal King bed, a double sofa bed, and Pullman beds that flip down from the ceiling. On newer ships like the Icon of the Seas or Oasis-class vessels, there are even more options including the Ultimate Family Suite or the Royal Loft Suite, which can accommodate up to six or even nine guests. However, many travelers find that booking two "connecting" smaller staterooms is often more cost-effective and provides the added luxury of two bathrooms—a major benefit for a group of five. It is highly recommended to book these high-capacity rooms as early as possible, as they are the first to sell out during peak family vacation seasons.
