In September 2019, we are considering doing as consecutive tours the Best of Eastern Europe in 15 Days Tour followed by the Best of the Adriatic in 14 Days Tour. There appears to be some overlap across these two tours in Slovenia and Croatia, although only 1 night in the same location (Plitvice). If any of you have done both of these tours, did you feel there was too much overlap?
Here is another related question:
We are currently planning to do three consecutive tours -- the two above as well as the Best of Germany, Austria & Switzerland in 14 Days. Of the three tours, we definitely want to do the Best of the Adriatic, but are flexible on the other two. If you think there is too much overlap with the Best of Eastern Europe tour, which other tours would you recommend considering that are relatively close geographically (i.e., among Central and Eastern Europe tours)?
