Taking a boat with 3 friends on a 7-day cruise through Croatia and possibly down to Montenegro. It'll be four of us, all in our 30s, all bachelors. There is no budget for the trip. Looking for the best beach clubs, or places to relax/party during the day. Same goes for night time; we'll be looking to enjoy quality restaurants and nightlife. In other words, sight seeing, hiking etc is not of particular interest. We have no itinerary aside from leaving split at the end of august and returning to split the first week of September. Your recommendations are much appreciated.
