A recent propulsion issue caused a delay in the dry dock completion for the _Allure of the Seas_, one of the world's largest cruise ships, at the Navantia shipyard in Cádiz, Spain. The ship was initially scheduled to leave on April 7, 2025, but problems with several propellers on three of its azipod systems required immediate attention. Shipyard staff identified the issue during a routine inspection and recommended repairs to avoid future dry docking. The cruise line decided to replace the problematic propellers, initially estimated to take three extra days. However, the repair timeline was successfully shortened to a day and a half, allowing the ship to depart on April 9, 2025, and head to Barcelona for its first post-repair cruise. During its month-and-a-half-long dry dock, the 15-year-old _Allure of the Seas_ underwent a $100 million upgrade, with an additional $2 to $3 million added for the unexpected repairs. The vessel now offers new dining and bar options, an upgraded Solarium, improved children's play areas like Splashaway Bay, and an exciting 10-story dry slide called the Ultimate Abyss. Passengers aboard the revamped ship will also enjoy the new Apollo 18: Lunar Landing escape room and updated accommodations with the Ultimate Panoramic Suites. The ship's first voyage after these enhancements is set to commence on April 11, 2025, with a 4-night round-trip cruise from Barcelona, marking its return to Mediterranean sailings after a 10-year break.
