Early Spring Ceremony?

Ok I seem to be getting a lot of mixed messages from the internet and from our family’s on this one. FH and I have a very important friend, who is a BM, and it’s very important to us to have her there on our wedding day. Unfortunately, she lives out of state and can really only make it in state mid March. The problem is that we live in Colorado and the high mid March is on average ~ 50 degrees, and we’re having a very hard time finding an indoor ceremony space within budget. We’re planning on having heaters and blankets for guests just in case, and despite reassurance, we’re still really worried about making our guests uncomfortable. Should we switch venues altogether to a venue with a better inclement weather plan (that’s slightly out of budget), or just hope for the best?
