This year myself and two friends are doing a study tour on a budget. I'm going to be faithfully recording our ins and outs on a travel blog that can be found here - http://kateinathens.blogspot.com/
The main idea is to help students like ourselves when going to Greece (particularly the Athens area) and show what goes right, and what goes wrong when in a foreign country where you can't even read the language nevermind understand it. Also to see how far our budgets get us daily and general information like where we ate, how long it takes to get to certain places and what lines we used to get there etc.
Hopefully this will be useful to people. We don't leave until the end of the month so watch out on the blog for daily updates. I'll post up a full travel report here (minus all the pictures and archaeological stuff) when I get back from Greece.
