We are planning a two week trip to Europe. We will spend 4 in Amsterdam, 6 days in and around Munich, and then a few days in Salzburg before heading back to Amsterdam to fly back to the US. We are doing the roundtrip to Amsterdam because we got a good deal using frequent flyer points and doing two one ways would be several thousand more.
The plan is to either fly from Amsterdam to Munich or take the Nightjet train. We will have two pieces of larger luggage, a size up from a carry on. We are wondering if that would be too difficult in our sleeper compartment or if we should just fly instead. We could also rent a car but it looks like a long drive although it could give us more time to explore.
