Our family reunion in Sept 2022 is for 16 people. We started looking in the Shenandoah Valley area, but now are zeroing in near McHenry, MD. There is not one place large enough, so we're trying to figure out whether two AirBnB's are right next to each other. Is there any reliable way to figure this out? I realize we can't get an address until paying. ANY HELP MUCH APPRECIATED. This is a lot of work figuring out how to accommodate everyone in the family's wishes so if we could get 2 houses right next to each other it would really be perfect.
