Plus Lake Placid is technically a village in the town of North Elba, while Big Sky and Kailua-Kona are census-designated places. Though I guess it's really semantics at that point since most of the other tourist towns are actually cities. Whatever.
Jackson Hole refers to the entire valley which extends way beyond the town. The town itself is just Jackson, Wyoming. I get why you chose to say Jackson Hole though. Even though it's not accurate or official, that's how most people refer to the town.
Humble brag: been to all except for Kennebunkport, so I skipped on that one and came back to it by process of elimination.
