Two stand out to me. Scottsdale, AZ, and Miami Beach, FL, are both destinations in their own rights. Many people fly to Phoenix and spend all their time in Scottsdale golfing. Most people that go to Miami actually go to Miami Beach to the point that many people may think of Miami Beach as part of the City of Miami.

Cambridge, MA, is probably right below Miami Beach or Scottsdale. The Harvard and MIT campuses are destinations in their own right to a degree.

Santa Monica is probably a good choice, too, with tourists who visit the pier.

Clearwater and St. Petersburg are also good candidates, although the Tampa Bay Area seems truly multi-nodal like the Twin Cities or Bay Area.
