Royal Caribbean operates a fleet that spans an enormous range in scale, from vessels the size of small cities to more intimate ships that feel closer to traditional resorts. The contrast shapes everything from onboard activities to the ports these ships can reach and the kind of vacation each delivers. Travelers weighing a booking often find the size difference the single most important factor in matching a ship to their preferences. ([1])
The Fleet’s True Giants
Three Icon Class ships currently top the lineup, each measuring 248,663 gross tons. Icon of the Seas entered service in 2024, followed by Star of the Seas in 2025 and Legend of the Seas in 2026. These vessels can accommodate more than 5,600 passengers at double occupancy and push the record higher when every berth fills. Their sheer volume allows for neighborhoods such as Surfside, an outdoor area built specifically for families with young children. Multiple pools, waterslides, surf simulators, and dozens of dining and entertainment venues fill decks that stretch far beyond what older ships offer. The design favors high-energy, resort-style cruising with constant options for every age group.
The Smallest Ships in Service
At the opposite end sits Grandeur of the Seas, built in 1996 and measuring just 73,817 gross tons. That makes it roughly one-third the interior volume of the Icon Class leaders. The ship carries about 2,000 passengers at double occupancy and retains the simpler layout common to vessels from that era. Its top deck features pools and sun areas but lacks the signature thrill rides and expansive water parks found on newer ships. Only a rock-climbing wall stands out among the signature Royal Caribbean attractions. Passengers who choose these smaller vessels often cite the quieter atmosphere and easier navigation as reasons they return.
Future Additions Shift the Balance
Royal Caribbean has seven new ships on order. Four more Icon Class vessels will arrive between 2027 and 2030, maintaining the current emphasis on maximum scale. One additional Oasis Class ship is also expected in 2028. A new Discovery Class series begins in 2029 with a second vessel due in 2032. These ships are being designed for smaller ports that cannot handle the largest vessels. They are also intended to eventually replace some of the oldest, smallest ships still sailing.
Matching Ship Size to Vacation Style
The largest ships function as self-contained destinations with Broadway-style theaters, ice rinks, multiple main pools, zip lines, and extensive dining districts. They suit travelers who want constant activity and rarely feel the need to leave the vessel. Smaller ships appeal to those seeking fewer crowds and a more relaxed pace. They often cost less per day and can access ports that mega-ships cannot reach. The choice ultimately comes down to whether a guest prefers the energy of a floating resort or the intimacy of a more contained experience.
