We are plaining to come to europe for 20 days and we are stying most of our time in like 10 day cannes. so but we wanted also go to Belgium ,Amsterdam and germany before heading to cannes. We will be landing in Paris and was thinking to spend 2 days there and 2 days in Belgium , 2 days in Amsterdam and 2 in Germany possibly duesseldurft or cologne then to cannes. so I am not sure if I should rent a car or get on the train so what is best way to plan this 10 days and what to used as transportation to stay in budget. any suggestion of where to stay and visit would also appreciated.
