The couple: Karen Kristian Beiler and Justin Beiler, married June 6, 2015, in Lancaster, Pennsylvania, Justin’s hometown. Each the child of missionaries, this Springfield, Missouri– based couple started globe-trotting early: Karen grew up in Tokyo, while Justin, the cofounder and owner of a coffee company, spent his teen years in Vienna. The plan: Three weeks in Europe—just the newlyweds, a rented Opel station wagon, and the open road. Shortly after tying the knot, they took off for their first stop, Budapest, where Justin had a work meeting. “We had no time to plan where to go,” says Karen, a wedding photographer, so they flew (er, drove) by the seat of their pants, developing their itinerary in transit. Go-to booking sites: Even though Justin says they were “prepared to sleep in our car,” that never happened, thanks to Airbnb and the HotelTonight app, both ideal for last-minute stays. The best finds: Vienna’s chic Ruby Sofie hotel (from $92.50 per night; ruby-hotels.com) and the bed-and-breakfast Val d’Orcia Pian di Meta-Mezzo in Tuscany (from $91 per night; airbnb.com). “The B and B was in a remote, beautiful place, and the host cooked a fivecourse meal,” Karen says. Favorite discovery: The couple quickly came to appreciate the perks of driving, which let them discover quaint country towns they otherwise wouldn’t have found, including Radda, in Chianti, Italy. “We got to see everyday life,” says Justin. “That’s the part of travel I enjoy.” Alpine adventure: After exploring Budapest and Vienna (including a visit to Justin’s childhood home), they headed to the Austrian Alps, with stops in Hallstatt and Zell am See. They didn’t let the cold and rain stop them from taking a ski lift to the area’s highest peak in Salzburg. “At one point you’re in the clouds, then suddenly you’re above it all and can see the mountaintops,” Justin says. Lessons learned: Stay positive! On a trip as impromptu as this, there are bound to be ups and downs, such as when the two returned to their room in Rome to find someone else in it! “Even when the hotels were not ideal, it became a funny memory,” says Karen.
