Arizona's great weather and scenic splendor are often enough to convince meeting executives to select the Grand Canyon State as a meeting site. Then there are the luxury properties concentrated in the two major metropolitan areas, Tucson and Phoenix/Scottsdale's Valley of the Sun.

Most of these offer full-service spas and expansive pool and recreation facilities--including championship golf courses. For links-lovers, desert golf courses lined with soaring saguaros and abutting boulder-strewn foothills are a special challenge. Phoenix's Valley of the Sun has more than 180 courses with three more under construction.

New to Phoenix's revitalized downtown is the Arizona Science Center and Phoenix Art Museum, plus new restaurants, theaters, and entertainment venues. And two new hotels have been announced, bringing the total number of rooms in the downtown area to 2,700 by 2001.

Scottsdale is looking forward to the fall completion of Scottsdale Fashion Square's expansion, making the mall one of the largest regional shopping destinations in the southwest, with 50 new shops. Scottsdale's downtown Waterfront Project will also add new shops, restaurants, and recreation and entertainment venues. In addition, the $3 million Scottsdale Museum of Contemporary Art will open in 1999.

Tucson is the repository of the state's history and its Native American, Spanish, Mexican, and pioneer cultural roots. There is enough to see and do in the city known as Old Pueblo to keep attendees entertained for a week. One not-to-be missed attraction: the Arizona Sonoran Desert Museum.

Tucson is also a great jumping-off point for visits to the southern part of the state. Among them are the vintage Western mining towns of Bisbee, Douglas, and Tombstone (site of the shoot-out at the O.K. Corral); the wineries around Sonoita and Patagonia; birding spots, such as Madera Canyon and the Chiricahua Mountains; and the artists colony at Tubac. A favorite side trip: Bargain shopping in the Mexican border town of Nogales, less than an hour from downtown Tucson.
