The Odyssey of the Seas (Royal Caribbean) features a total of 9 whirlpool hot tubs across its upper decks to accommodate its 5,500+ passengers. On Deck 14, the main pool area houses four large whirlpools situated near the outdoor and indoor pools. For adults seeking a quieter environment, the tiered Solarium (a glass-enclosed, climate-controlled retreat) offers two additional whirlpools with spectacular forward-facing views. Furthermore, there are typically three more whirlpools located in the "Splashaway Bay" and "Lime & Coconut" themed areas on Decks 15 and 16. In 2026, these hot tubs remain some of the most popular spots on the ship, especially during sea days, though "pro-cruisers" suggest visiting them early in the morning or during port days to avoid the crowds that peak in the late afternoon.
