Our wedding ceremony and reception are both outside, in Candler, NC (just outside of Asheville) on Saturday Oct 12th. It's looking like the highs will be in the 70s and lows possibly in the 40s. Wedding is at 5pm, reception from 6:30 - 10pm. Then campfire after party (everyone is staying on site in cabins). My question is: should we get tent sides? And what about heaters? The heaters are very pricey. We were trying to keep the cost down and we also like the way an open tent looks more, but we also don't want people to be uncomfortable. Thanks!
