THE CELEBRITY QUEST, a former Pullmantur ship, will introduce 25 ports of call in Europe to the Celebrity brand when it begins a European program in April 2008. The 710-passenger Celebrity Quest will sail out of Rome on 14-day "Best of Italy" cruises, marking the Celebrity Expeditions brand's inaugural Europe season. The vessel joins the Celebrity fleet later this year along with its sister vessel, the Celebrity Journey, also a Pullmantur ship.
