When Princess Cruises launched this 3,560-guest ship in 2013, fans of the line's traditional style of cruising held their breath. They need not have worried. The updated ship adds just a touch of contemporary, but is still classically Princess and offers plenty of popular Balcony Staterooms. Royal Princess was followed by a succession of five Royal Class siblings, from 2014’s Regal Princess to 2022’s Discovery Princess, and was refurbished in 2018.
