My FI and I attended a wedding in Montana last summer and it was a great trip. We got to go hiking and visit the national parks the week before the wedding and it was a blast. The wedding we attended was at Holland Lake Lodge...it was beautiful, but small...and not near Bozeman, we actually flew into Missoula, so not sure that's any help to you, but I'm happy to contact the bride for her vendor list if you're interested!
