[5][6] Throughout her service Carnival Ecstasy has cruised from ports in the United States to Baja Mexico, the Bahamas and the Caribbean.

[7][8][9][10] After Hurricane Katrina, the ship spent six months in New Orleans serving as quarters for evacuees and relief workers.

[11] In February 2022 Carnival announced that due to uncertain times in the Australian cruise industry, Spirit would re-home from Sydney to Jacksonville, Florida.

As Ecstasy was attempting to reach an anchorage north of the Miami sea buoy, the vessel lost power and began to drift.

One passenger required medical treatment as a result of a pre-existing condition and was categorized as a serious injury victim because of the length of her hospital stay.

The National Transportation Safety Board determined that the probable cause of fire aboard Ecstasy was the unauthorized welding by crew members in the main laundry that ignited a large accumulation of lint in the ventilation system and the failure of Carnival Cruise Lines to maintain the laundry exhaust ducts in a fire-safe condition.

[13] On July 1, 2007, David Ritcheson, the victim of the April 22, 2006 Harris County, Texas assault incident, jumped off the deck of Carnival Ecstasy and died.

[17] 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.
