We stayed at Gloria's Airstream during the winter and it hit the low 30s during our stay. It definitely did not feel that way! Gloria was extremely understanding of our ever changing plans for arrival. She made it easy to find the Airstream even at night. Although smaller than initially thought (the pictures were updated after booking, but they reflect the true size of the Airstream now), it was very comfortable, which is exactly what we needed after a day at the slopes. Friendly and comforting through and through!
