+1 for that. Best bet would be to leave Chennai by 4 PM so that we can be in Salem by 10 PM, get a good nights rest and start early (before 6 AM) for Ooty. I guess it takes about 5 hrs from Salem to Ooty? so that we can be in Ooty by 12 PM max. As for me -I'd be travelling next week and hope to get back by Friday in which case I can definitely (and prefer to) start on Friday late afternoon.
