Uniworld is now leasing two of the Crystal ships from Riverside Luxury Cruises. This is confusing. Riverside bought the 5 Crystal ships and said they would be bringing them in to service. Then we heard that Transcend is using the old Crystal Mahler in 2024. Now we hear that Uniworld will be running the Mahler in 2025 as the S.S. Elizabeth. This is a 3-year lease so the ship may go back to Riverside.
