In a significant change to the cruise industry, Royal Caribbean has become the second major cruise line to staff lifeguards at its pools. Starting with Oasis of the Seas, Royal Caribbean is rolling out a water-safety program that includes a lifeguard stationed at each pool during its hours of operation. To date, only Disney Cruise Line has hired shipboard lifeguards, and other cruise lines say they follow the policy seen at many land resorts where no lifeguards are provided and guests swim at their own risk. Royal Caribbean said its program is a comprehensive one to raise awareness amongst guests about the importance of vigilance while enjoying water features on their ships. Swim vests will also be offered to children ages 4-12, and a water safety presentation will be made in the Adventure Ocean kids program as well as a separate session on water safety for teens. The new water-safety program will be implemented fleetwide by this upcoming June.
