no on-street parking, please. And plenty of dependable electrical wiring, smooth walks/parking to allow rolling carts, a kitchen area for refrig/microwave/food snacks. Is this someplace that people will actually sleep at? I go to a retreat at least once a year where we stay for 2 nights--we share rooms 2-4 per room and have a private bath per room. When we have overflow and have to use an additional cabin with 16 beds and a "gang" bathroom, we get people upset about getting stuck in those arrangement due to over sleeping area and large group shared bath. Good luck--retreats are so fun!
