I was going to say the same on Swiss hotels plus well, doing almost anything there: four beers and a game of pool = eighty five euros, a pizza for one = twenty five euros etc. (this is outside of Zurich too).
Road tolls in France used to be quite a bit less also, surprising - it now costs pretty much double what I used to pay down to the south and back. If heading a little further east though as Mark says, it's no further and much cheaper simply to drive through Luxembourg and Saarland instead.
Hard to beat a long road trip!
