And I thank each and every person for their input.
We all make choices.
Given my age and the normal problems that come with aging, mobility issues and budget, I believe that a cruise works best for me.
I began to sail Norwegian because NCL was the first cruise line to offer studio cabins for solo passengers and they continue to be revolutionary in what they offer the solo passenger. This will be my 9th cruise with Norwegian. I get rewards and discounts. I know the score with NCL. I know what to maybe expect. But the cruise I am going on this October is a 4,000 plus passenger ship and sold out. I think that I will probably stick with Norwegian until it is over, either me or my money, whichever comes first.
Norwegian does offer cruises to those places that are less popular but then it might be more difficult for me to get to the port we sail from. I have to look into those cruises but traveling to and from a port might also be an issue. Only partly is it money. My age keeps me from being as adventurous as when I was young.
Most river cruises do not offer cabins for one person. Usually you have to pay for two. I wish I could sail Viking but usually you have to pay the full single supplement.
I became attracted to Japan because of posts on this site. Now I am obsessed with visiting Japan or maybe another Asian city. I think that I would like to explore another continent.
When I booked this cruise leaving from Barcelona, I had no idea that Barcelona was so popular and over visited. Now I know. That's part of the learning.
Many of these cities and countries became over visited by their advertising of themselves which I no longer see. Once they wanted visitors. "If we advertise, they will come" Travel writers were schmoozed And visitors came and came and came. And now "Hey wait a. minute".
Cruise lines continue to have heavy advertising on TV. So do the airlines. So do hotels and booking sites such as Booking. Persons are healthier and live longer. They have more time and money, even those on a. budget. And they get hooked by the ads.
However since I usually sail in Fall, there are supposed;y smaller crowds and costs are less. Weather may be cooler but can also be unpredictable. I would also consider sailing Spring but never in the summer. I travel in what was once known as the shoulder season but this season has been heavily promoted including on this site. The shoulder season is now very popular for travel. Crowds are smaller but places are still crowded. Costs are less but still can be costly.
Maybe what cities and countries can do is advertise the reality of what it is like t visit some of these places. For instance, they could show the crowds in Rome in 90 degree weather in summer with a caption "Do you really want to come:" Just an example on how to discourage people from coming.
I was watching YouTube videos about Rome and someone was posting a video with "Rome in July" and showed the massive crowds trying to visit the Trevi Fountains, etc .
