Especially on how far these places are and how to travel between them.
I'll be landing by train at Chennai Central at 8am (Would Perambur or some other station be closer?)
I have some work at Anna Salai, Chennai - 600006 at 1pm
Then I have a flight back at 10pm
Any other info - good hotels / Five stars, good places for breakfast / lunch / dinner etc etc would also be greatly appreciated!
