I take them into the camper and demonstrate how to poop and flush sucessfully, using clear words and gestures. This is an icebreaker for sure. And extremely necessary as we quickly learned after our second guests didn't understand the camper toilet and didn't ask. It was a dis-ass-ter.
Seriously, we greet them at our locked gate, give them the gate opener and accompany them into the camper. I have a little intro speech, describe all the things they can access and use, show them how to work the heat and air. If they have a dog with them I help them introduce it to the ranch dogs.
Good coffee and good 'creamer' is so important. I stayed in an Airbnb in San Antonio. It was perfect and the hosts were wonderful but the coffee they provided was cheap and stale (undrinkable) with fake powdered creamer. Bleech. I would rather have had nothing provided and known ahead of time to stop at a store on the way. The first morning was a disappointment.
We provide ground coffee regular, dark roast and decaf. Filters, a coffee maker and a Melitta drip filter. Tea, herbal, green and regular black tea, sugar, artificial sweetener, shelf stable soy, shelf stable whole milk, canned fizzy drinks (real juice and soda water no sugar added.) Hot cocoa mix for the kids.
We do provide breakfast items but they have to cook and clean up after themselves. You could say that no breakfast items are provided but coffee, tea, drinks are welcome by anyone and don't spoil very quickly.
If I didn't already have the camper set up for guests before we started the Airbnb I would probably get a Keurig. Then the coffee, tea and chai could all be in pods. Since our camper was already set up I just went with what we already had.
