These questions are fun, upskilledotter! Thank you for starting the thread. To take on the travel ones . . .
I am partial to New England as a sample of America: the Berkshires (a lovely vacation area in western Massachusetts), Vermont, Maine, and some places on the outskirts of Boston. Concord is a picturesque town that offers great historical sightseeing and a nice half-day walk along Battle Road. Plimoth Plantation, in Plymouth, is a very good living history museum about the Pilgrims.
I will also give a shout-out to my native Great Lakes region. Chicago is a vibrant city with good food and good museums, as others have already mentioned, and from there one could drive north to quieter towns such as South Haven. During COVID, my extended family and I took a driving tour of Michigan's Upper Peninsula, visiting the Soo Locks, the Great Lakes Shipwreck Museum, Tahquamenon Falls, and the Ojibwa Museum in St. Ignace, which is on the site of the 1671 Jesuit mission. The Upper Peninsula is a different world. It can be frustrating both to get there and to travel there, but it would plunge you into a culture that is very distinctively North American.
When planning holidays, many Americans focus on the U.S. When I was a child, only 5% of U.S. citizens had a passport. (I should add that in those days, it was possible to visit Canada and Mexico without a passport, and many people did not count that as "abroad."). A typical holiday for us was either Lake Michigan or a city break in Chicago. We also visited Amish country in Indiana and Ohio. Later, as a teenager, I was taken to Boston, New Orleans, the Great Smoky Mountains, and the Rocky Mountains.
Passports are more common now (Google says half of U.S. citizens now have one!), and well-educated people, especially on the coasts, travel overseas regularly. France, Italy, and Portugal are very popular, as is the Caribbean. Greece is having a momentthat seems to be where all my friends want to go! More adventurous travelers go to other continents, too, but often with a distinct focussome people make multiple trips to East Asia, others to South America, others to Australia and New Zealand.
