I'm trying to figure out the best passes to buy for our family's summer vacation in Europe. We are 2 adults and 2 kids (ages 7 and 9). Here's the itinerary:
Day 1: arrive Munich airport
Day 2: Munich -> Salzburg
Day 3: Salzburg -> Fussen (Bavaria), Germany (rent car in Fussen)
Days 4-5: Bavaria w/ car
Day 6: return car Fussen -> Lauterbrunnen, Switzerland
Days 7-10: Lauterbrunnen and Gimmelwald (multiple cable cars and buses involved in plans)
Day 11: Gimmelwald -> Frankfurt (rent car in Frankfurt)
Days 12-13: Rhine Valley w/ car
Day 14: return car Frankfurt -> Berlin
Days 15-17: Berlin
Day 18: Berlin -> Munich
Day 19: Fly home
All connections listed above will be via train, plus we will be using public transportation at all points when we don't have a car rented. This gets pretty complicated, especially when considering the 2 kids and the various options (Eurail, point-to-point, Bernese Overland Pass, or some combination of multiple ticket types). Anyone with expertise or experience want to provide any guidance? All advice is appreciated!
