I stayed in one of the geodesic domes, which are behind the main lodge. There are 7 domes that share 3 bathrooms, which are in a different building. You receive a key upon check-in to unlock one of 3 doors to a private bath (sink, toilet, and shower). I was a little worried about having access to a bathroom given all 7 domes were rented during my stay and only 2 of the 3 bathrooms were usable...but never had to wait. The two things the bathrooms need are a mirror and additional wall hooks. Perhaps a mirror in the domes as well. The domes do have a small air conditioner (which I used during the day), along with a heater (which was needed at night when the temps dipped into the 40s). I loved sleeping in the dome...the bed and pillows were comfy. My only complaint was the people arriving later in the evening. I would fall asleep, then be awakened by vehicles approaching (you park next to your dome). Unfortunately for me, the guests in both domes next to mine arrived late, so it was nonstop noise as they parked, unloaded, talked out loud, shut car doors, and locked their car doors (beeps/horn sounds). The domes really should be farther apart OR require all arrivals be before 9 PM. I loved the location of the lodge to Great Sand Dunes National Park. I do photography so staying so close to the park allowed me to take late afternoon/evening and daytime pics (the dunes look different depending on the time of day). I would definitely stay here again! Super friendly staff as well.
