At that time, Velachery was kind of outside the city and so it was an exotic location for setting up such a facility. These days, access to this Complex is much better and by all accounts, it is quite crowded - which, of course, is a big complaint for the users.
That complaint is offset to a large extent by the quality of the coaches. Most of the coaches teaching here are state level coaches and that brings in a lot of traffic. The Complex discourages walk-in swimmers. But if you want to get in here, you can sign up for the 12-day swimming classes - but then, don't complain if you find the pool too crowded!
