The only things I can see that you would absolutely need would be Coffee and Filters.
The coffee pot takes the regular basket large style Filters.
There are plenty of wash cloths and towels in the room to use.
We don't really restock stuff. Nice Disers often leave what they don't use behind.
If it were me I would just bring what you need to be sure you have it.
You never know if Nemo isn't defrosted well and leaks all over everything and ruins stuff.
I brought coffee filters, coffee, and disposable coffee cup, ziploc bags...
And bought Milk, Juice, water, yogurt, fruit, bread, chips from garden grocer.
