A power outage at the Royal Caribbean terminal in Galveston, Texas, caused significant delays for passengers boarding the Mariner of the Seas on Monday, January 19, 2026. While the weather conditions were favorable, the cruise terminal's power issues led to a 2-hour delay for guests, both those already on board and those arriving for their voyage. The situation is particularly challenging for those with post-cruise travel plans, as the Mariner of the Seas was returning from a 4-night sailing and was scheduled to depart at 3 p.m. The cruise terminal's equipment, including escalators, was non-functional, and customs and security processing took longer than usual. This incident has sparked curiosity about the impact on future sailings, with the next departure scheduled for Saturday, January 24. While the Mariner of the Seas has a margin for delay, the situation highlights the potential for knock-on effects on post-cruise travel plans. The cruise terminal staff are working to resolve the outage, and guests will be updated on any itinerary changes. The Mariner of the Seas, with a capacity of 3,114 guests, is homeported in Galveston until October 2026, and the situation serves as a reminder of the importance of power reliability in cruise terminals.
