What is the difference between Jackson Hole and Jackson, WY? | United States Forum | Fodor's Travel Talk Forums

I'm really confused about these 2 towns -- Jackson Hole and Jackson, WY. How are they related to each other? Which one is the airport? Our flight is going to Jackson, WY. Which one is the downtown/sightseeing place? Where should we stay? Know any nice campground in the city?Thanks!
