I stayed at this CG a few years ago, and the first thing that struck me while I was in line at the checkout window was a couple signs...
"Any verbal abuse directed at Park staff will not be tolerated and you will lose your reservation."
Hmmm I thought...
I had similar power issues and just moved myself to a spot that had it's own supply (most sites share a power post, with only one 30A and one 15A receptacle). I was lucky though, the park wasn't full.
In a nutshell. ..... Old park run by off-shore investors who are not RV'ers.
Being the only show in town though, they really don't have to do anything to remedy anything.
