Grand Tetons Lodging question
 

We will be spending 4 nights in yellowstone at Canyon & Old Faithful and 3 nights in Grand Teton Area. I have looked at several VRBO's in the area and wondering if any of you have stayed in either Teton Village or Wilson? Any advantages or disadvantages to either place? Would one be better than the other in regards to exploring GTNP? Also I've noticed that most properties do not have AC. We are going end of August/beginning of Sept. Can I assume we won't need it? Thank you for any and all advice.
