That's a good list.
I would also add Sherman Island, CA, South Padre Island (SPI), TX, Floras Lake, OR coast, and Lake McConaughy, NE (where most of Denver kites in the Summer).
If you're planning a vacation to a big city then some of the more remote destinations may not be your best bet.
You should also consider each location's wind season. For example, South TX (SPI & Corpus) windy season is just beginning as East & West coast locations are shutting down in the Fall. That's why you'll see lots of people from Canada and Northern US latitudes at SPI during late Fall, Winter, and early Spring. You should be able to find great wind at one of these locations throughout the entire year. Hawaii's (Maui & Oahu) wind is the most consistent in the Summer but its warm so many kiters go there late Fall, Winter, and early Spring.
