Haus Rohrbach was a very enjoyable winter getaway for my hubb and I and our 2 daughters, ages 8 and 5. The property has it's own sledding hill,an outdoor hot tub, snowshoe trails right behind the inn, and great xcountry skiing within a couple miles.
For future visits with kids we'd stay in a suite in the main haus.For romance, one of the detached suites with the incredible views.
Leavenworth looks like a fairytale mountain town at night during Dec-Jan when it's all lit up.
The down side is winter reservations are hard to get, many places (incl Haus Rohrbach) are booked a year in advance but you can always try for openings.
