I would totally recommend a "fix it person".. When we had our latest tour to sort out problems we took Yakup, who is a lovely guy and has an equally lovely wife. After we sailed through all the "problems" we though we had, with Yakup's perfect translation and help, we asked him how much. When he told us, Phil gave him double, as he said it was soooooo worth it. We actually had to force Yakup to take it..
Why put yourself though hassle when you can get it done smoothly and trouble free.
