Yes, Oasis of the Seas features a high-energy, glow-in-the-dark laser tag experience called "Clash for the Crystal City." This activity was added during the ship's massive "Royal Amplified" transformation and is located in Studio B, the ship's multi-purpose ice skating rink. During designated hours, the rink is covered with a specialized floor and inflated with futuristic, neon-lit obstacles. The storyline pits two clans—the Yetis and the Snowshifters—against each other in a battle for control of a mystical frozen city. This is a family-friendly activity that is typically included in your cruise fare, though it requires a reservation via the Royal Caribbean app as it is one of the most popular "sea day" activities. In 2026, the experience remains a highlight for teens and families, offering a fast-paced "off-world" adventure in the middle of the ocean. It is worth noting that participants must wear closed-toe shoes to play, so be sure to pack sneakers if you plan on joining the "Clash."
