I'm planning on getting married on October 31st and want the ceremony to be outdoors in Northern NJ probably around 4 or 4:30pm. Is it too cold to have a 15-20 minute ceremony outside at that time of year? I'm really set on having it outside because the view at the venue is gorgeous. I would supply little blankets or hand warmers for people as well. The only other date they have available is September 5th and then I would not be able to have the fall theme that I am so in love with.
