Swap wife - first time with couple

We are planning a wife swap. Full swap. All are consenting. However the ladies have both made a request to get to know the gents first.
They know each other well but not on that level, just as friends. They need alone time with couples swapped, not to do anything but just to kinda get to know each other more personal. So coffee dates are out ofnthe question but maybe something similar whereby after they can have a few moments just alone and more personal.
The experts amongst us can share some idea or suggestion
