The altitude at Manor House is about 5,400'. As far as elevation in Colorado goes, this isn't terribly high - but it's probably higher than what you're used to. To prepare yourself for the altitude, we suggest the following: 1) Drink a ton of water! For the week leading up to your trip, really try to increase your water intake. 2) Give your body time to adjust. If you can arrive a few days before our wedding, we encourage you to! 3) Avoid strenuous exercise. 4) Be aware of your alcohol intake - booze feels stronger at a higher altitude. 5) Oxygen bars & oxygen canisters - these are all things you can find around 16th Street mall. If you're feeling light-headed or short of breath, take advantage of these Colorado amenities. ...Really, just drink more water and you'll be fine :)
