Lughnasadh Wedding?

I just found out via a friend that our wedding is planned for Lughnasadh eve.
I don't know a whole lot about Pagan holidays (please correct more or inform me better if I get any of this wrong Pagan folk!) but my impression from reading around the interwebs is that this particular feast/holiday is about harvest, bounty and things coming together.
It was traditionally at time in Ireland where people would handfast, and have a trial marriage for one year. It sound to me like a terribly appropriate time to get married! Neither my Luke nor I are Pagan, however we have a lot of respect for a lot of the elements of Paganism that I am aware of, especially when it comes to respecting nature, the elements and the natural flow of things. We think this coincidence is very cool.
Any of you who are Pagan, are there some ways that we may be able to integrate a small part of that holiday into our wedding, paying respect to it so to speak, without being offensive since we are not ourselves Pagan?
