Tata Group firm Indian Hotels Company Ltd (IHCL) will bring its Vivanta and Gateway hotels under the 'Taj' brand and exit the other two brands as part of a major re-branding exercise, a top company official said. IHCL’s strategy to upgrade and leverage on the Taj brand comes as at a time when the company is seeing growing threats from major international hotels in India in the recent past. These hotels will now be divided into four sub-categories—Taj Hotels, Palaces, Resorts and Safaris depending upon the location and nature of the properties.
