Stick to the route you have decided, roads are awesome all the way. You will mostly find traffic in the Delhi Jaipur route and just before Mumbai .Do your best to avoid getting into Mumbai else you will be forced into its maddening traffic!!!.. Around 1500 bucks toll... Ahmedabad - Vadodra express way is a dream road, even better than the Mumbai Expressway! Lots of road side eating places! 5 days is more than sufficient! I did it in 3! :twisted: I would recommend leaving by 4 AM and driving till 3 in the noon... Have fun & Drive safe!
