I would ignore the bad reviews. As long as you understand that this is primarily a retreat for the episcopal church and the rooms are suited for that purpose, you will just love this location.
The rooms are a bed and a bathroom. If you want amenities, they are absolutely there. If you think about retreats, this is about community and amenities are outside of a personal experience It’s the first time I have kayaked this year on their beautiful lake, roasted marshmallows on a campfire, they had coffee anytime you wanted it in a central location. All you had to do to get staff’s attention was simply say good morning or good evening and the attendant are right there to help you. it is a very special place close to Brevard, mountains, biking, trails, hiking trails, and basically anything you would want in the mountains.
