Celebrity Solstice underwent an extended 47-day shipyard and modernization period at Seatrium Tuas Boulevard in Singapore from January 15 through March 2, 2026. The project was the first in Celebrity Cruises' $250 million Solstice-class modernization program and combined scheduled maintenance with substantial passenger-area refurbishment. New and reworked venues included Sunset Park, the Boulevard Lounge and Boulevard Bar, an expanded Sunset Bar, Craft Social, Trattoria Rossa and Fine Cut Steakhouse, along with expansion and refreshing of The Retreat. All 1,479 staterooms were included in the modernization, with four new stateroom categories introduced and AquaClass accommodations receiving additional spa-inspired features before the ship returned to service.
