I will be traveling solo to Armenia for about a week this fall. I would love to hook up with a two or three day tour to see some of the country. In Istanbul there are tourist agencies on every corner. In Beirut I had to work hard to find even one. What are the odds of finding something in Yerevan? I don't want to book anything in advance if I don't have to. I prefer to be more spontaneous if possible. Thank you for any information you may have.
