Gone are the days when motels and caravan parks were run by Mum & Dad teams who got up early to make breakfasts, stayed up to welcome latecomers, took time off in the middle of the day and still managed to answer the phone if you rang at a reasonable hour. 

Nowadays such places are run by big chains whose employees keep strictly 9 to 5 hours onsite and don’t like you ringing them up, even in those rare cases where they actually provide a number to call.
