For those of you who care about this issue, please be aware that many businesses in Savannah crank up the A/C and then open the doors to attract customers. Upon making a polite complaint about this practice, I got an extemely abusive reply from a business owner. This was a pretty stupid thing to do to a tourist, considering the power of word-of-mouth advertising. While Savannah has its lovely spots, you can bet I will never, ever set foot in that city again.
I hav never posted in this forum before and it is certainly not my intention to offend anyone. I hope other travelers can profit from my experience.
