Aurora

Penthouse Suites: Two forward-facing duplex suites come in at a generous 953 square feet. There's a living and dining area downstairs, while the bedroom is upstairs.

The Glass House: This novel restaurant and wine bar concept, created by British TV presenter and wine expert Olly Smith, has a list of more than 40 wines from around the world, to be paired with tapas-style small plates.

Watering Holes: There are a variety of bars onboard; Anderson’s Bar is possibly the most refined cocktail venue at sea, while Champion’s sports bar appeals to a lively crowd.

Facilities for kids: Unlike P&O's adults-only ships, Aurora has plenty of family-friendly spaces. The Reef — P&O Cruises’ free onboard program for 2- to 17-year-olds — has dedicated deck space and pools, plus a soccer school during the summer.

Active cruisers: The Crystal Pool has a retractable glass roof that is closed in cold weather, allowing swimmers, as well as those chilling out in the whirlpools, to enjoy their sport in all climates — handy during cruises to the Baltic and Norwegian fjords. There’s also a sports court with a golf simulator.

Anglophiles: It's easy to get immersed in British culture on this ship, where you can sit down to afternoon tea with scones and clotted cream and jam, or order a pint from a pub with more than 70 British beers.

Fiery curries: The ship's main self-serve restaurant, Horizon, offers "Curry Nights" when Indian and Goanese chefs prepare a selection of spicy curries that aren’t for the fainthearted.

Its an Older Ship: Despite its 2014 refurbishment, this ship is still more than 15 years old — it doesn't compare to the line's flagship, Britannia.
