I don't know about number 7 - most of the USA is actually pretty nicely temperate. There are some exceptions like death valley (3000 sq mi) or the chihuahan dessert (about 25000 sq mi in the USA), or some parts of Alaska, but we're talking about a very small area of a 3.7 million sq mi country. If those aren't your thing, I do recommend skipping them. UAE is only 32000 sq mi and it's all very very hot.
Otherwise that's all fairly accurate. But Disney world is pretty damn great.
