This thread reminds me of sci-fi (Star Trek in particular). They orbit a planet and visit a few places on one small area, they then say they have visited the planet.
What really makes a visit? Shopping? That seems a bit odd.... seeing the sights? You could do that (depending on the "sights") from a train or airplane while moving and never setting foot in the country. Talking to the people? Only if you speak the same language (know the others/etc).... seeing things that only that country has that no other place has, nor may ever--that requires being on the ground to appreciate? That might be a bit closer.
If someone went to England and said they ate, stayed in a hotel, and did not do much else, I would wonder why they wasted the money going. Or if someone went to Australia and stayed in the city, away from the water.... or other similar things (like not seeing museums/etc).
