For romance, Cavtat Day Trip is hit or miss.
The easiest, calmest half-day escape — a scenic ferry across the bay to a genuinely lovely, low-key town where you can swim, stroll the promenade and eat by the water without the Old Town frenzy. The honest catch is it's quiet by design, so thrill-seekers will find it sleepy; it shines as a restorative counterpoint, not a highlight reel.
