I saw Cassie's enquiry which is same as mine really. I have found accommodation and reasonable return flights to Thessalonika but can only find private taxi transfers averaging about £180+ which is ridiculous! almost as much as cost of flights.
I don't mind getting coach from Thessalonika but would like to hear from anyone who has done this.
Also I will be travelling mid September and have not been able to find bus timetable / prices for this time. Read Alex G Love's reply to Cassie but the website he recommended is all in Greek!
Would love to hear from anyone with tips soon as I haven't booked anything yet but don't want to lose prices quoted for flights and accommodation.
