I went on the Montenegro day trip from Dubrovnik in July of 2012. It was a very enjoyable day, well worth the money spent. The tour guide was incredible. He was a fountain of information about everything- culture, history, geography. He even tells good jokes! People should be aware, however, that this trip involves a lot of time on the bus. There is a lot of driving involved. I enjoyed this aspect, though, as it provides a great opportunity to see the countryside and a lot of smaller towns. I strongly recommend this trip.
