Greetings from the Florida Panhandle
First off, welcome to the Forums. We're glad to have you with us.
Sorry about the campground thing, but stuff happens. As to the air conditioner not cutting it, you may need to put some reflective material covering your windows between the glass and the curtain. If your a/c unit is blowing cold, try covering some of the windows and especially your skylight with some of that silver reflective insulating material from Lowes.
When it's super hot out, letting all the light in just kills the air conditioner.
