What's there

Condiments, tea, coffee, sugar, beer, wine, soft drinks, marmalade, jam etc.
You only need to replace drinks, biscuits and crisps on a like for like basis.
Plenty of wood for the lounge stove (I have an inexhaustible supply).
There is a bread machine with all the ingredients except butter so be brave,
follow the instructions for granary bread and enjoy the smell of fresh bread in the morning.

What to take

Slippers if you have them otherwise use the hotel slippers in hall cupboard.
Food for eat-in meals and butter for the bread machine.
Suggest you take enough food for 24 hours and then stock up at the local supermarkets in Banff and Fraserburgh.
There are no shops within 5 miles of Pennan.
Tesco in Ellon (15 minutes beyond Aberdeen and 45 minutes from Pennan) is a good place to stock up on your way to Pennan.
