Levent is one of the guides I have been corresponding with.
One of the guides--don't remember who--wanted $70 pp for Ephesus and was taking 14 people. I got another quote for much less for a group of 4. I know you get what you pay for and I'm sure the guide that wanted $70 pp is excellent but I hate to be one of 14.
I have only received prices from two guides thus far because we are still workingon itineraries. I'm trying to decide what to see and what to miss. We can't do it all and I'm worried about burnout. We're planning on spending additional time in Istanbul so we need to save some physical and mental energy for the end as well!
