Celebrity spending $400 million to renovate fleet

The Retreat Sundeck, making its debut on the Celebrity Edge, will be a feature on all Celebrity ships.

Celebrity Cruises plans to spend $400 million over five years on so they will look more like the Celebrity Edge, a ship due in 2018.

Between 2019 and 2023, Celebrity will redesign and reconfigure all staterooms on its nine ships.

The suite lounge known as Michael's Club on some ships will be rebranded as the Retreat Lounge, a space making its debut on the Edge. There will also be a new Retreat Sundeck.

A new Oceanview Cafe, an international marketplace concept, is coming to the older Constellation, Infinity, Millennium and Summit ships.

Over 11,500 cashmere-covered mattresses and bed sets will be installed. Storage in cabins will be reconfigured along the lines of Celebrity Edge to maximize efficiency, Celebrity said.

"This is the largest investment our brand has ever made to modernize our fleet," Celebrity CEO Lisa Lutoff-Perlo said.
