Amadeus is using its internal test bed to experiment with an advanced hotel search engine along the lines of the Affinity Shopper technology it unveiled for flights in 2009.
Amadeus hotel distribution boss Hugo Ehrnreich says the company wanted to develop extreme search technology across more of its travel portfolio.
He described the hotel booking engine as the new "user interface manifestation" of shopping technology that the GDS is now working on.
"Air + hotels gives much more value because it creates packages."
The company is working to integrate hotel aggregators in the back-end so web content sits alongside traditional GDS chain hotel content.
"We had to build the shopping engine to pull the content and functionality together and Wallaby is the application of that -shopping technology in the back-end that can be used to cross or upsell and presented in a calendar display.
"In B2B channels you will see this technology is already being used and it will start to become more sophisticated."
Amadeus Hotels Plus already offers some of the functionality but future plans include a b2c solution for OTAs and other travel companies.
Lufthansa was the launch partner for Affinity Shopper, the airline version of the technology while OTA eTraveli partnered with the GDS for the Extreme Search product.
Amadeus has yet to sign a UK partner for the flight solution.
