This is for August 2011.
We're flying into Dublin (about $700) was the cheapest that I found.

We want to travel to:
Ireland
Amsterdam
Finland
France
Italy
Rome
(maybe Spain)

We are planning on couchsurfing (at people's houses who we know)
but in case we can't do that, and we know we cant everywhere,
we will be staying in hostels.

How much approximatly would this cost possibly (from someone who has done it),
we're not going to take any tours.
