The staff was amazing...they allowed early check -in at no extra charge. Spacious rooms, very quiet, bed was comfortable. On Wednesday we decided to go ahead and leave due to more storms moving in, we were checking out Thursday anyway. They gave us a credit for the night even though it was late afternoon when we left. This wasn't our first time there and it won't be our last.

This property met all our expectations for our stay. Excellent facilities, friendly and professional staff and an excellent location to downtown Gatlinburg. We would stay there again if ever we're visiting Gatlinburg.
