Innsbruck-Paris, Budget?

Travel Info
I intend to go this summer from innsbruck, austria to Paris. I am willing to stay for 4 nights in Paris. Any Idea how much would that cost?
I am not much of a shopper, I am ok to stay at student hostels.
Sightseeing list includes Eiffel Tower, Louvre, and EuroDisney.
Whats the minimum budget (Trains, Stay, Sights, In-Paris expenses)?

hi,

I think you can get out with 20 euros /day for accomodation if you stay in "auberge de jeunesse" (in France)

have a look on this site for booking:

20 euros/day for fooding if you like sandwiches.
For visits, it depends, Eiffel tower and louvre should be arround 10 /15 euros (actually don't know the exact price)
