I would like to stay in Harligen one night and in Alkmaar the next night and I would like to take a bus that goes on the A7 and the Breezanddijk to Den Oever. I read somewhere that the Arriva Bus company operates this route “in summer.” I will be traveling in May. Is that considered summer? The Arriva web site doesn’t allow any trip planning beyond March so I can’t use that to determine the answer. I don’t want to travel from Harligen back to Leeuwarden. Thank you in advance.
