My backup plan for something like this would be to always carry a couple of good quality extension cords.
The camping site probably had a 30A service as well as a 20A service. These would be on separate circuit breakers on the pedestal...
I would rig something up to use the 20A service along with the 30A service to get it cooler... i.e. have a portable air conditioner that would plug into a 120VAC standard wall socket and use their 20A service to power tat up etc...
It is also possible to rig up the shore power adapter cords to plug the 30A service into one of the 50A zones and the 20A service into the second 50A zone of your trailer just to run the second air conditioner... Those two 50A zones in your trailer are wired separately...

A couple of ideas to look into to see if it might be feasible for you to do in this respect...
I know in my case I really don't need the air conditioners as most of my camping is OFF-GRID Camping running everything off the batteries. I am very happy to only have a couple of those fantastic roof fans running in the early evening and all night playing with the cool night air... If I am at a creekside camp setup I will be in hog heaven haha...
I can't remember the last time we have used our roof mounted air conditioner...
we all have our different way to love the outdoors haha...
