I be agree with all the items the others have said. I might be repeating but we also put in a Keurig coffee maker with coffees, creamer, sugar packets, a variety of tea, hot chocolate, hot apple cider packets. A nice wine opener, we’ve recently added breakfast items such as individually wrapped pastries, oatmeal, frozen breakfast sandwiches.
I like to be sure we have plenty of nice wine glasses, drinking glasses, and large coffee mugs.
Napkins, both paper and cloth. Zip lock bags, foil, Saran Wrap.
Basic condiments and spices.
In addition to main appliances, a microwave.
Mixing bowls, pots and pans.
Enough silverware for each guest xs2.
