At a recent wedding in the foothills of South Carolina, a wedding was almost postpond because of the extreme heat.  The 150+ year old stone building didn't have air conditioning and the temperature outside was over 100 degrees.  Flowers as well as the attendees were wilting.  A guest went to a local convenience store and purchased 2 cases of bottled water to give out to the people waiting for the ceremony to start.

At the last minute  the Mass that was planned was canceled, as that would have been almost an hour long.  Instead a 7 minute ceremony was performed.  This experience is a very important lesson to remember when planning your wedding during the summer months or at a very hot destination.  Be sure that the venue is air conditioned.  If not, have a back up plan for either fans to be brought in, or another location that is air conditioned.  The bride was very upset that she could not have the ceremony she had planned.  But she and the groom also didn't heed warnings from their wedding planner.
