Celebrity Cruises, which clearly has decided that bigger is better in the upscale cruise segment, on May 21st announced it has confirmed its order for a fourth Solstice-class cruise ship which will enter service in Fall 2011.

The as-yet unnamed 2,850-guest cruise ship will follow sister ships Celebrity Solstice in Fall 2008, Celebrity Equinox in Summer 2009, and Celebrity Eclipse in Summer 2010, bringing Celebrity's total fleet to 11 ships.

Celebrity's fourth Solstice-class cruise ship will have the larger standard staterooms, 90 percent of which will be outside, and 85 percent of all staterooms with verandas, that characterize these 122,000-ton ships.

"Ordering a fourth Solstice-class ship is obviously a testament to the demand we've received from travel agent partners and travelers alike for more cruise vacation options with Celebrity," said Royal Caribbean Cruises Ltd. Chairman & CEO Richard Fain.
