Campsite fees

Hello everyone, we have been campers for a long time, but so far always with a tent. Have bought us a used caravan a few days ago. I find the camping fees are quite high. Also the differences between the places are very different in terms of the price. I find that some place operators do not miss anything to invent ever new additional fees. Tent size, dog per night up to 4€, garbage fees per night and head, shower coins, electricity connection etc. Why can’t you calculate something like this? If you leave the dog outside. But for a dachshund 4€ per night I find ditching. Certainly there are so-called luxury places with ADAC seals that offer some, among other things animations, connected golf course etc. Of course something like that has to be paid. I have the impression that many “normal place” operators now attach themselves to this price level. How are your experiences?
