Spa Towns, Two by Two

Pick a spa town in Europe, the kind with warm pools and slow mornings. Short flight, easy pace, no itinerary to defend. Mornings for soaking, afternoons for wandering cobbled streets with nowhere to be. Bring another couple and split a table at dinner, swap stories about the water that's supposedly good for everything. You'll come home loose-shouldered, a little sun-touched, already planning which town to try next.
