The lifestyle focused mid-segment hotel chain Ibis, a part of the French hospitality major Accor Group, will add over 500 keys across four properties, taking total inventory to over 4,000 by 2022. While Ibis, since its entry in 2008, operates 3,500 rooms across 19 properties (Ibis & Ibis Styles hotels) spanning 13 cities, its parent Accor operates over 9,500 rooms spread across 51 properties under 10 brands across 21 cities in joint venture with Interglobe Hotels, an arm of holding company of budget carrier Indigo since the past 14 years. The expansion is focused on three cities Mumbai, Bengaluru and Goa which are already functioning almost at pre-pandemic levels, though the revenue normalisation may take a quarter or two, Sylvain Laroche, director of operations, at Ibis India told PTI.
