While most cruise lines are adding cabins to existing ships and building newer and bigger ships (think Oasis of the Seas or NCL's F3 ships), Crystal Cruises is actually decreasing the passenger capacity of Crystal Serenity. During a November dry dock, the luxury line will convert 12 deluxe staterooms into 8 penthouses. Fleetmate Crystal Symphony will not be getting the new cabins.
The penthouses are some of the most highly sought after cabins on Crystal Serenity. They're 403 square ft. with a large balcony and living area, and feature butler service, a bar stocked with wine and liquor, Jacuzzi tub and walk-in closet. Penthouse guests can order room service from Serenity's specialty restaurants (24-hours) and receive complimentary pressing.
Following the dry dock, Crystal Serenity will have a total of 72 penthouses and 32 penthouse suites. Four of the new Penthouses will be able to connect with penthouse suites for groups traveling together.
There will also still be 70 category AA deluxe staterooms. A representative from the luxury cruise line assures us that with so many deluxe staterooms available, no pre-booked passengers will need to be switched to another departure or room type because their original cabin has been converted into a penthouse.
