Hello everyone! I plan on buying a one-way ticket to Europe, Stockholm to be exact, for May 2008. After a lot of research and stuff, I've pretty much come up with the cheapest plan I can think of to get to Stockholm...

1. Chicago to Frankfurt International Airport (via AirIndia for $302.10)
2. 2-3 day lapse for transport from Frankfurt Int. to Frankfurt-Hahn (12 Euro, not including accomodation)
3. Frankfurt-Hahn to Stockholm S. Skavsta (NYO) via RyanAir (19.48 euro)
4. Bus over to Stockholm (unsure of cost)

So, to my questions...

1. What fees and charges can I expect from RyanAir aside from the price of the ticket?
2. How much of a lapse do you feel is necessary to get from Frankfurt Int. to Frankfurt-Hahn?
3. I want to give myself enough time to get from Frankfurt Int. to Frankfurt-Hahn, but if I have an extra day or two, is it possible to sleep in the airport?

My 1st question (about RyanAir fees) is my biggest concern. Thats why I entitled the post as I did! Thanks in advance!
