I have lived overseas twice (Saudi Arabia and Germany) working as a civil servant for the US Army during the 80s and early 90s.
I had only been to Canada and Mexico before I moved to Riyadh, Saudi Arabia in 1981.
I traveled a lot during that period and never had a sense that I would be back to some places. As it turned out, during that period, I was able to go back to places like Rome, Paris, Venice, much of Southern Germany, Austria and Switzerland.
After retiring in 2010, we have taken overseas trips frequently, generally 2 or 3 a year except during the two year COVID shutdowns. I have been back to some places, but most of our travel has been to places that we haven't seen. Now I have been to 78 foreign countries and still have a wish list for a few more.
When I first traveled to Europe in the 80s, fewer Americans did so. They were either military or civilians stationed in Europe or wealthy people. This has changed a lot. Way more people travel overseas now. Airfares are comparatively lower (considering inflation) than they were in the 80s. I remember paying $1200 for my Son to fly from Georgia to Germany for the summer in the late 80s. Until recently, I could beat that price.
Example, I love Italy and have been there several times. Been to Rome twice and Florence twice. Been to Venice 5 times. Frankly, having been to Venice 5 times, I have no desire to return there, however, would love to return to Rome once more.
At first, my travels focused on historical places, but after much travel, visiting scenic places has become more a factor. Scenic places like the Galapagos Islands; Cruise to Alaska visiting Glacier Bay and the Hubbard Glacier as well as Denali post cruise; up the coast of Norway to the North Cape; visiting the Great Ocean Hwy in Australia; cruise around the Horn of South America; visit to Hawaii.
I know people that have cabins in the North Carolina mountains and only go there for there annual vacations. I can't imagine doing that at all.
