LHI will install TravelClick's iHotelier Central Reservation System at its six international hotels, which include properties in London, Hong Kong and Melbourne.
The hotel group hopes that underpinning its online booking facilities with TravelClick's software, and centralising sales in the process, will increase online activity.
Brett Butcher, senior vice-president of sales and marketing at LHI, said: "With a single click, room availability and rates are displayed clearly on one screen with captivating photography of our hotels."
LHI is forecasting that 10% of its total room revenue will come from its own website this year, rising to 30% by the end of the decade.
