No Keurig. If you are driving, you could pack yours.
We have groceries delivered from Garden Grocer. Even with a car, an hour to grocery shop out of our precious vacation time is too much. And we aren't from the region, grocery store layouts vary a lot by region, so it isn't time effective. But I know there is a Wal Mart with groceries nearby.
You'll need coffee filters - Mr Coffee basket style. And anything edible. And laundry detergent (if you are going to do laundry). Cleaning supplies are provided (dishwasher detergent, paper towels, bathroom tissue), although some members bring their own Lysol, bathroom cleaner, counter spray or other cleaning products, since your room won't get cleaned during a week long stay. (We can do anything we've needed to do with dish soap).
