I guess its too late to suggest you route your trip Budapest to Prague to Ljubljana? There are nonstop flights in that direction....

Thanks all for your suggestions and help. We’ve got it figured out now.

Much appreciated!

curious. how are you going to do it?

Thank you for asking, James E. We decided to nix Lake Balaton and add an extra day in Budapest and will gain another day in Ljubljana. We will take the bus and arrive during daytime hours. This seemed to be our best bet...
looking very forward to our visit!

Its too bad you couldnt find an intermediate stop on the way to Ljubljana.

When we went to Dubrovnik from Budapest it bacame the perfect opportunity to see Belgrade. Something that we otherwise might have skipped. The flight was Budapest to Belgrade for about $50, two nights in Belgrade (but I would have thought it worth it if we had spent one night), then another $50 flight to Dubrovnik. For me that is easier than 8 hours on a bus. But I know a lot of people are very adverse to short flights. I will say, it they go through major airports I would be too. But the airports are more like bus stations in places like Belgrade, Dubrovnik, Podgorica, etc.... And Wizzair is as close to a bus with wings as you can get....
