I found Callaway Gardens to be a huge disappointment, primarily due to the complete indifference shown by the management and staff at the facility. The gardens themselves are very average, and the facilities are rather old and overpriced. There is very little to do at Callaway, or in the town of Pine Mountain. Restaurants at Callaway are extremely limited and very expensive.
Overall I found the whole experience to be a very big disappointment, and I would strongly encourage others to consider spending their money at an alternative venue.
Cons: Expensive, little to do, sub par facilities
