It marked a departure from the initial Costa ships that emerged when Carnival Corporation acquired the line in 2000, emphasizing a distinctly European and exceedingly luxurious ambiance.

One striking feature of the Costa Toscana is the clever utilization of color to distinguish its public spaces. For instance, one can readily discern the rich forest greens of the Kartell Caffe on Deck 8, situated amidships, or the vibrant fire-engine red of the aptly-named Campari Bar on Deck 7.

P&O Iona

P&O Iona also holds 5200 guests and has a crew of 1800 Making it one of P&O’s largest cruise ships. As the sibling vessel to Arvia, Iona stands proudly as another splendid offering from P&O Cruises. She solidifies its position as one of the largest British cruise ships for the foreseeable future. Arvia and Iona share striking similarities, both epitomizing modernity and spaciousness, making them perfect choices for couples or families. While Iona may not offer the extensive array of features like rock climbing walls and surfing simulators found on Royal Caribbean ships, it excels in providing excellent kids’ clubs with a wealth of diverse activities.
