We had a lovely wedding at the village - candlelit ceremony in the church, and then a walk to the reception pavilion.However, though the reception pavilion is well-roofed, it can be cold in the shoulder seasons if the wind comes up. (And very hot in the church in the summer, of course!)
Remember the obvious: Pioneer settings, camp settings, conservation settings (Kortwright) and anything outdoors is NOT climate-controlled, so plan accordingly, warn your guests to bring wraps, bug spray (and a change of shoes - high heels on grass and cobblestone are treacherous). It may be obvious to you, but it won't be clear to those who haven't visited the venue.
