I'm on the Portrait of India tour right now and am blogging our experiences. I've only done the initial few days but I'll continue and will post more here as we continue on the trip.
You can see the beginning of our trip at https://www.mikeandjudytravel.com/2024-3India-01.htm
I usually improve the blog after we get home so treat this as the "first draft of history'.
[Added note: no set of pictures and text can convey the real experience of being there. However, Tauck does essentially the same things on the same tours so this can give you an idea of what you’ll do on this tour.]
