airportShuttle property Null safety
The hotel provides guests with a chauffeured van or bus to and from the airport. Can be free or for a fee. Guests may share the vehicle with other guests unknown to them. Applies if the hotel has a third-party shuttle service (office/desk etc.) within the hotel. As long as hotel provides this service, it doesn't matter if it's directly with them or a third party they work with. Does not apply if guest has to coordinate with an entity outside/other than the hotel.
