Florida - WDW - park hopping with a car and parking charges

i am wondering if i get out and come back in, or if park hop with my car, if I will have to pay parking each time i get out and in, or if parking is just once into the entire complex.

Parking is only charged once a day. You will get a card to go on your dash that will let you into all the parks' parking lots.

thanks very much. appreciate this info.
