is there anything else in walking distance besides the airport, like shopping?
No,but if the shuttle bus will take you
No not really
Across the street you'll find a bowling alley and the convention center. If you don't mind walking about 15 minutes you'll run into a Taco Bell and a McDonald's. On that same street is a little store called Retail 4 Less which is a little outlet store.
