We are planning a small destination wedding to Colorado and currently live in Ohio. I just recently became aware of altitude sickness from other forum posts and am now concerned. We haven't booked anything for the wedding yet and while it's my dream location, I'm not sure if we should avoid it because someone in my immediate family has diabetes and isn't in fit shape. I'm not sure how the altitude will affect them if we just have a ceremony in Breckenridge or Denver area but no physical activities in the mountains. Recommendations and experiences?
