Hello, we have two girls ages 5 and 8. We will be in Europe for 3 full weeks, with 7 full days dedicated to Austria (non travel days). We do have a rail pass (yes, I know it was probably a poor decision to purchase that) and about 3 days of travel on it. We'll be starting our trip near Salzburg, coming in from Munich through Bad Reichenhall. We then need to head to Paris on day 8 for the last 3 nights before flying home. I know Paris is inconvenient to get to from Austria, it's just how things wound up.
I'm interested to know where you'd suggest we stay, and what places are must sees. We prefer the small villages and lakes and mountains. If possible, we'd head west to Basel before heading to Paris from there - simply because it seems we could break up the journey to Paris if we slowly make our way there on the train through Austria. How easy are the Austrian trains to reserve? Thoughts?
