Chennai is many things to many people but a happening address for posh hotels it was not, at least not till a couple of years ago. Now it appears that every hotel major wants a slice of the city’s upbeat hospitality sector (See: It’s raining hotels). The figures are startling: the number of premium rooms has gone up from 1,800 in FY07 to 3,021, a jump of nearly 65% in less than four years. Another 522 rooms will be added once ITC’s Grand Chola opens next month. By FY15, the number of premium rooms in the city would have risen to about 5,010, or 180%, if all the projects coming up meet their deadlines.
