My wife and I booked a trip from August 27th-Sept 11th, 2017 for 15 nights starting and finishing in Turin, Italy. I've been to Switzerland (and Chamonix, France) myself back in 2009. My wife has never been to Europe. I want to take her to see some of the places in Switzerland that I went to the first time. My wife's really wants to see Plitvice Lakes in Croatia (which is up there for me as well). If we're going to head as far as Croatia, I've always wanted to see the northwest corner area of Slovenia as well (Lake Bled, Lake Bohinj and especially the Soca River area). We also plan to either start or finish off with 2-3 nights in Cinque Terre.
While 15 nights is great, I also realize this is a lot of places to visit. At one point, we also pinpointed Hallstatt in Austria and a couple nights in the Dolomites as well. Those may just have to wait for a second trip someday. I've been doing a lot of research and have come up with a couple of ways to get around our trip, but there's a few questions I'm running into.
My biggest dilemma is how to get around in Croatia and Slovenia. When I was in Switzerland 7 years ago, the Swiss Pass was the way to go. We'll probably do that again for our time there as the Berner Oberland/Zermatt are the locations we'll likely end up. However, to get around the Lake Bled/Soca River Valley area, it almost seems like having a rental car would be really helpful. I've only ever driven in the US and Canada, so I'm nervous about driving in a country that drives on the left side. Are my fears justified or is it easier than expected? And is the public transportation system good enough that a rental car really isn't needed? One thing to keep in mind is that I'm a landscape photographer, so being at my locations early in the morning and later into the evening is sometimes really helpful. Lots of public transportation doesn't run until after sunrise/before sunset in many places. I had considered looking into renting a car in Villach, Austria and using it to travel to Bled, Soca River Valley, etc. If I went this route, would we be better off using the rental to drive down to Plitvice or would it be just as easy to train down there, then fly to Switzerland from Zagreb or Split?
The other big question is that I tend to try to cram too much into a trip. As a landscape photographer, I'm trying to maximize my time always. My wife is usually okay with this (she's a photographer as well, but of a different type) as we always get to see a LOT on our trips. But I also don't want to wear us out so much that we don't get to enjoy it. Since we're flying into Turin, if we decided to cut this trip in two, we would probably save Slovenia/Croatia for next time and go when the autumn colors are in full swing, as we have a free hotel stay in Switzerland that expires at the end of 2017. Does 2 nights in Cinque Terre, 4-5 nights between Slovenia/Croatia, 5-6 nights in Switzerland and likely 2 nights traveling between (spent somewhere in Italy or Austria) seem too ambitious?
