That is pretty much what I am saying. I know it is tight, but as an average it should work out though right? We would like to do a couple of museums, I see in Madrid the majors are free. The Louvre looks awesome, but not required.
You are really pushing it, imo, on that budget. Obviously people like undocumented immigrants live on very little, but Paris is not inexpensive.
In Madrid, the majors are free at specific times (can't remember which).
The Louvre is free one evening per week - again can't remember which.
I hope you have a fridge in your room or something.
If you don't mind saying, what are you paying for lodging? Is there any possibility of getting a better deal?
