This is very much a family holiday setting.. We knew this because we took our to children to Cullen every year in the 1980's and early 1990's. Our children are raising their own families. We are now in our 70's and came up to refresh our memories of happy days of long ago. Reasonably good weather, Great scenery, beautiful sunsets, and looking at the lit sky in the North at Midsummer midnight. What more could an older couple ask? Yes, a corker of a macaroni and cheese lunch at Christie's Garden Centre, Fochabers. And the local people are friendly and helpful.
WiFi fine. Broadband so-so but that would be outwith to owner's control. Being used to gas cookers, we had initial problems acquainting ourselves with the electric oven. We reported this to the owner.
We had our car. Necessary because the 35 bus is I think one per hour. There is no baker, butcher, petrol station or bank in Cullen; and no ATM. Buckie is 5 miles away. Drive, or catch a bus, or go on-line (that won't fill your petrol tank). Or walk - if you are fit!
To recap, there is plenty for the older client to enjoy e.g. Glenlivet, Portsoy, Baxters on Speyside. But - Cullen is a child's paradise. (We were very impressed with the upstairs accommodation in the cottage, and with the facilities available for the younger holidaymaker.)
