Dear Sir,
Let me first know that do you welcome tourists in your tourist group from INDIA?
I feel confident that the Rick Steves company does not discriminate or exclude people on the basis of national origin (or race or religion), so you would certainly be welcome on the tour. That being said, this forum is composed of travelers who give advice on a volunteer basis, so for specific information about tours, you would need to use the 'Contact Us' feature at the bottom of the page.
