Please do not back out. There will likely not be hook-ups but it is not a big deal. Each town has fill and dump sites and if you ration, you may only need to do this in the middle of the week. Generators will run till about 9 or 10 and then most of them shut off and open windows. It usually cools down but there may be a night or two you need to run it longer. We have done it many years and it really has never been an issue. I really only remember one night about 10 years ago when it was like 95 at 9:00. I just kept drinking beer until sleeping was not an issue. Getting going the next morning was but after some coffee and some food, all was good. It is a really good time for all.
