FACTBOX-Las Vegas Strip under construction

(Reuters) - Developers are expected to add about 23,000 luxury hotel rooms to the Las Vegas Strip between now and 2010.

That number has fallen by about half from a year ago as the weak economy and credit constraints led several developers to reconsider their plans.

Following is a summary of casino-hotel projects currently under construction:

-- Encore at Wynn Las Vegas: 2,034 all-suite hotel tower, 72,000-square-foot casino, convention and meeting space, restaurants, nightclub, swimming pools, spa and salon, and retail outlets.

Located just north of, and adjacent to, Wynn Las Vegas.

Due to open in December.

Owner: Wynn Resorts Ltd

-- Caesars Palace: new 665-room hotel tower, including 75 luxury suites, additional meeting space, a remodelled and expanded pool area and other improvements.

The expansion is slated to open in mid-2009.

Owner: Harrah's Entertainment

-- Fontainebleau Las Vegas: 3,889 hotel rooms (including 1,018 luxury condominium-hotel units), 100,000 square foot casino, 353,000 square feet of convention and meeting space, a spa, 3,200-seat theatre, 291,000 square feet of retail space and numerous restaurants and bars.

Located toward the northern end of the Strip at the corner of Las Vegas and Riviera Boulevards.

Expected to open in fourth-quarter 2009.

Owner: Fontainebleau Resorts

-- CityCenter: Consists of Aria, a 4,000-room gambling resort; three luxury non-casino hotels including Mandarin Oriental, the Harmon Hotel, Spa & Residences and Vdara Condo Hotel; Veer Towers, the development's only strictly residential building; approximately 2,600 condominium residences; and the Crystals, a 500,000-square-foot retail and entertainment district.
