Hi, I'm trying to do a weekend, 2 day trip from Paris to see Giverny, Etretat, and Mont Saint Michel. I would ideally like to do all of my transportation by train, bus, other public transport, etc. or at least most of it that way. I know there's trains/buses that would get me to Giverny, but it is hard to find out about how to get to Etretat and Mont Saint Michel from there. Also looking for good cheap places for my overnight.
