As the distance is very short, you can be at the airport in a very short time. Good tips for best experience in Old Town Budva if you like to spend more time would be Casper bar. You also have bars which are popular at night El Greco and Jeff bar. But as you are in a Old town you have to expect high prices for food and drinks. What we really recommend as the locals is restaurant Porto with great food (Mediterranean and Montenegrin) near old town of Budva with a view on local port.
