Cruise News Today — August 25, 2022. Carnival Cruise Line has followed in the footsteps of Royal Caribbean International and Celebrity Cruises by allowing unvaccinated guests to self-test before their cruise. Celebrity Ascent marked another construction milestone this week when both the keel was laid and a coin was welded to the ship. You may want to think twice before checking a bag for your next cruise. In the month of May, over 200,000 checked bags in the U.S. were lost or sent to the wrong destination. Cruise line stocks were up for CCL, RCL, and NCLH.
