If you don have much time, then u can spend around 3 full days in Kodai.... otherwise 5 or even 6 days is really good, where you can chill out. AS said, Ooty is too commercialised, however Kodia is also reaching there, but still slightly more pristine. taking a walk or cycle or jog around the lake area is really lovely anytime of year. good restaurants (to cater to Indian and NRI and foreigner toungues) are plenty.
