Wondering if Portugal Tour is less strenuous than the Slovenia/Croatia Tour.
I've been on both tours and I felt like we did a bit less walking and stairs on the Portugal tour than on the Adriatic tour. Having said that, however, neither tour is overly strenuous IMHO. It does involve walking on cobblestone streets, walking and then standing during tours, and some stairs and a number of hilly streets. I did feel like there was a bit less bus travel time on the Portugal trip. But only you know your comfort and fitness levels.
