charghes at grantown -on -spey

 my son and family are new to caravaning  they booked on-line at grantown  for 4 persons as per form after paying in full they realised they were charged for adults    when they phoned grantown to explain that it was 2 adults 1child almost 3 and 1 child 8weeks old they were told they charge for all children  this is no way to encourage young famlies to caravaning as no children at that age would be useing any site fascilites
