Fly into paris stay a night, get to Normandy for a couple of nights, get to Lux for a couple of nights and than Munich...flying out of Paris to get back. I was going to try and just do public transportation and trains/planes between countries but than seen I can rent a car for the entire trip for less. I am also concerned about venturing out to the WW2 sites since they are outside of the cities it seems, I think Ubers and such might get pricey. Would it be a bad idea to just rent a car?
Any recommendations are greatly appreciated
