As part of the Evolutions of Fun upgrade program, in mid-2007 the Ecstasy was renamed the Carnival Ecstasy to match with the rest of the Carnival branded ship names in the fleet. Continuing with the upgrade program, in the fall of 2009 the ship was given a 28 day dry dock and a major multi-million-dollar refit. During the refit, 98 ocean view cabins were converted into balcony cabins along the mid and aft sections of the ship, some of the suites located on the Upper deck received extended balconies, the kid's wading pool area on the lower aft area of the ship was removed and converted into an adults-only Serenity area with sun loungers and two hot tubs, the aft pool was removed and converted into the Carnival WaterWorks water park with waterslides and fountains which also replaced the original waterslide at the main pool and the original kids wading pool, the main pool area was refurbished and given a resort-style appearance, a younger teens area Circle "C" was added, and various interior renovations and enhancements were made.
As part of the Evolutions of Fun program, the Ecstasy underwent changes to match the rest of the Carnival fleet, including a rebranding and renovations. This process continued with a significant update in 2009 that included new amenities and features.
