I am planning to visit Iran in the beginning of April with my wife. I also want to visit Mashhad. So far I have been able to find, on the internet, only LetsgoIran who offers a trip that will take us to Tehran, Shiraz, Esfahan, Mashhad and Qom. I notice most of the package tours are for people more interested in the ancient history of Iran. Mashhad is not to be found on these tours. LetsgoIran offers a tour that may meet my needs, i.e. see both the ancient and spiritual sides of Iran. I want someone to help me from personal experience how they found LetsgoIran or suggest one, again from personal experience, who is reliable, economical and meets a North American traveler's standards. Neither I nor my spouse speak Farsi that's why we are looking for a reliable tour operator. Thanks for the help.
