Kotor is the single best day trip out of Dubrovnik: a UNESCO fjord-like bay, a walled medieval town and prices roughly a third lower than Croatia.
The drive is 90 km along the coast. Expect 2 to 2.5 hours door to door including the Debeli Brijeg border crossing, or slightly less using the Kamenari–Lepetane ferry across the bay.
Guided group day trips depart Dubrovnik daily from around €55 per person; private cars with an English-speaking driver run €90–€140 one way and let you set your own pace.
Pickup in Dubrovnik around 7:30am, border at Debeli Brijeg, photo stop above Herceg Novi, boat out to Our Lady of the Rocks from Perast, then two to three hours free in Kotor for the Old Town and — if you are fit — the 1,350 steps up to San Giovanni fortress. Many tours add a Budva or Sveti Stefan viewpoint before returning by 7pm.
Rental cars from Croatia usually need a green card insurance extension to cross into Montenegro — confirm with the rental company before you book. Parking in Kotor is outside the walls (€1–€2 per hour). In peak August, cross before 8am or after 4pm.

About 2 to 2.5 hours for 90 km, including the Debeli Brijeg border crossing. In peak season border queues can add 30–60 minutes.

Yes — the Bay of Kotor is a UNESCO World Heritage site, the coastal drive is one of the best in Europe, and food and drink cost noticeably less than in Dubrovnik.
