Hi Lesley
I made sure I did not go on the tour of Mumbai after the Kerala trip as I knew about the traffic jams. I took a rickshaw, with another lady who too did not fancy going, to the hotel and rested in one of the rooms booked for freshening up for the rest of the group to come back. They too hardly saw anything and did not even get a chance to take any photos! You do need a couple of days in Mumbai to see the main sites. I think Hils is doing the right thing by spending additional days in Mumbai.
