May not be able to run the microwave and a hair dryer and the AC all at once, but you should be able to run everything you need.
In a perfect world, unfortunately most campgrounds do not have perfect nor adequate services for the number of sites they have.
the electrical services per code is NOT required to handle the full load capacity of all the outlets. Most parks will be using all those outlets on a busy weekend, therefore your voltage will be on the low end causing your amperage to be on the high end.
You don't want to use the micro, water heater, a hair dryer and the Air conditioner at the same time. The starting load on the Air conditioner alone will be 20+ amps, water heater - 12 amps, 1000 watt microwave - 9 amps. 1500 watt hair dryer - 12 amps.
Then there is the power inverter that is running all the time that uses a share of the 30 amp capacity.
The only way you will be able to tell what you can run at the same time is by trial and error and most likely will not be the same at every location.
The DW found out the hard way a couple weekends ago. The campground was near capacity. She was running the microwave when the Air conditioner fired up causing our 30 Amp main to trip.
FWI those main breakers in your electrical panel get weaker with each time they trip and after a while will either not trip or trip well below their rated capacity... to low is safe, too high is dangerous and can lead to fires.
