Yup! I've stayed at one. Actually every year for a sporting event in Gray Summit, MO.
The NO AC ALLOWED comes into play depending on the weather and how many RV's are there. Especially the number of big coaches with 2 AC's sometimes 3 ac units on them. All turned on full blast.:(
And to the people who blatantly disregard this rule? Please do all of us a favor and just LEAVE!
We had people disregarding the NO AC and it shut down the power in the CG. Causing everyone else major inconveniences. :R
