IN a study by Tourism Features in 1991 on domestic tourism some interesting points surfaced. While the figures have, in all likelihood, veered towards more prolific travel, they are notch marks for any historical perspective. The survey found that 41.8 per cent of the urban domestic tourist took vacations once every year, 15.4 per cent once every six months, 16 per cent once every two years and 8.7 per cent don't take vacations at all.
