Remember hot pots from your days in college? I stayed in a hotel room this summer that provided a little "comfort station" for guests with a hot pot, mugs, and various beverages like teas, hot chocolate, and instant coffees.
How simple! I made a little spot under the night stand in my guest room to do the same. I could add some cookies or muffins before guests arrive. This allows them to take their time before getting up in the morning or lets them wind down before bed.
It would be just as simple to make up a basket if you don't have a shelf.
What kinds of special things do you do for your overnight guests?
