We are setting the date for early November, would it be too cold for an outdoor ceremony in Las Vegas? I looked up the average yearly weather forecast and it says low of 43, and a high of 67. The venue we have in mind has the option to add heat lamps, but I'm not sure if it will be warm enough. Has anyone held their outdoor ceremony in late fall before? I really don't want my guests to be cold, and I definitely wouldn't have to be in a situation where we are saying "I d-d-d-d-d-d-d-o"
