If not “posh,” at least look for services, a lounge, and access to some sort of transportation.
Long before on-board weather, I, along with my wife, a friend, and his wife ended up making an enroute diversion to get a better handle on the weather ahead. Not knowing any better, we stopped at an airport in New Mexico that had no staff, an FBO building with a couch that we were afraid to sit on, and not even taxi service to town, let alone a crew or rental car.
It was the fastest turn around ever. And literally a “turn around.” The weather was worsening toward our destination and, before similar weather reached us, we ran to the plane, “kicked the tires, lit the fires,” and headed to a Class C we passed earlier.
(The airport was Truth or Consequences. Although we felt it was very appropriately named at the time, there has been a major turn around since then)
