Stuff you should know about Breckenridge.
Breckenridge, the town, sits at 9600 feet. If you don't live in the mountains, this will most likely take some getting used to. Drink lots of fluids BEFORE flying, and hydrate on your way up. You will want to consume at least 3 litres of water a day. (No we are not exageratting. At least 3 litres.)
Breckenridge, and much of Colorado, is high altitude desert. The absence of moisture is what makes the snow so exceptional. (That's right, the moisture content of snow can vary widely.) However it also causes dry skin, chapped lips, dehydration, and respiratory issues. Use the humidifier in your room at night.
Altitude sickness is quite common for even the most seasoned visitors. Common symptoms are a feeling of nausea and general cold. Fluids are the solution. Seriously, start drinking water before you get on that plane.
Breckenridge is know for its cold temps, wind, great terrain, and excellent snow. While other resorts may suffer, Breck usually has good snow and fewer people. However it can be very cold and windy up top. (We ski at 13,000 feet.) Pack an extra layer and a face mask.
Finally, consuming alcohol at altitude increases its effects. Use that information as you see fit.
