"Portonovi, Montenegro Mountains, pine forests and preserved medieval villages ring the sumptuous, fjord-like Bay of Kotor. More recently, slick super-yacht marinas have been popping up along the shore. The latest is Portonovi Village, home to the first European outpost of the glossy One&Only marque that is more often seen on the beaches of Mauritius and the Maldives. It has pulled out all the stops here. Children start the day devouring doughnuts at breakfast before joining the melée at KidsOnly, a club for treasure hunts and telescope making, science labs, and stick-raft building. Parents lurk by the pool in Chanel beachwear, ordering Veuve Clicquot by 11 a.m. The most health-conscious focus on recalibration in the heavyweight Chenot Espace, which offers medical-grade diagnostics and transformative treatments from wellness pioneer Henri Chenot. While the Chenot diet is legendary, and effective, it would be a shame to miss out on all the other sensational food (and perhaps foolish to attempt a detox on a family holiday). Sabia turns out the best Italian dishes this side of the Adriatic—don’t skip pizza-making in the kitchen. In summer, the kids’ club is open for movie nights on request, meaning parents can slip off to sushi suppers at the Tapasake Club. It’s not often that indulgence can be this family-friendly.
