Hospitality Net

Hyatt.com is now fully integrated into Hyatt's reservations systems and customer databases and boasts improved navigation and personalization capabilities. The site supports Hyatt's varied customer groups - individual and business travelers, Gold Passport members, travel agents and meeting planners. By personalizing the experience using ATG personalization capabilities, Hyatt encourages its members to visit and utilize the site for reservations.

"After deploying Critical Mass and ATG, we are now delivering a uniquely Hyatt experience online and we expect to see reservations continue to grow dramatically over the next year," said Joan Lowell, vice president Electronic Distribution, Hyatt Hotels Corporation. "We expect our customers to take advantage of the personalized offers and site content, driven by ATG, to improve their travel planning experience time and time again."

Critical Mass also designed and implemented a custom Content Entry Tool, enabling Hyatt's domestic properties to manage and modify their own hotel Web sites. ATG personalization, also a feature of the site, allows Hyatt to target promotions and manage relationships online.

"Using ATG's Relationship Management Platform and Critical Mass' Content Entry Tool, marketing managers can create customized marketing messages about hotel promotions and features, all within Hyatt's corporate brand guidelines," says Neil Clemmons, senior vice president, Critical Mass. "This solution reinforces the Hyatt brand across property sites while allowing local property content changes from hotel managers."

"In the travel industry, personalized service is expected and the benchmark for quality service is set very high," said Fumi Matsumoto, vice president of technology, ATG. "Critical Mass and ATG have helped Hyatt take their customer service to the next level by understanding the needs of their customers and servicing them accordingly."
