I will be on the 14 day RS Adriatic Tour which starts in Ljubljana and ends in Dubrovnik in September. If you have been on this tour it would be helpful if you can offer suggestions for sites/activities during the free time we'll have, as wells as where to spend some time before or after the tour ends.
We'll be arriving 4 days before the tour, Our current plans is to spend three of those days in Lake Bled (maybe too much), and one in Ljubljana before the tour (but are open to changing that); and staying two days in Dubrovnik after the tour. Any recommendations on day trips from there or how best to spend some of that in those two places. From Dubrovnik I'm debating between Cavtat and one of the Elaphite Islands (Lopud??). Also can you suggest a tour company for doing the Skojan caves from Ljubljana. I was thinking of doing that during the extra day on Ljubljana, but the company I looked into (Viator) does not offer on that day (a Saturday)
