• Power outage at the Galveston terminal affecting Mariner of the Seas
• Rescheduling of guest boarding times by at least two hours
• Manual luggage handling and processing delays due to equipment failure
• Itinerary flexibility allowing the ship to recover lost time at sea

Although the cause of the electrical failure was not immediately disclosed, terminal staff and maintenance professionals worked throughout the day to restore services and manage the flow of over 3,000 travelers.

Despite the late start for the subsequent five-night itinerary to Costa Maya and Cozumel, the ship is expected to maintain its scheduled port visits. The planned day at sea following departure provides a buffer, allowing the vessel to increase its cruising speed to make up for lost time. Royal Caribbean indicated that guests would be updated on any potential itinerary adjustments, though significant cancellations appear unlikely.

Other cruise lines at the port, such as Carnival Cruise Line, were also present during the day, highlighting the widespread impact of terminal-side infrastructure issues on regional cruise operations.
