Hi, Angie! Just follow the signs to the theme park of your choice. When you get to the toll plaza, you will pay the Cast Member to park. For future reference, you can find the current parking prices by clicking
here. Scroll all the way to the bottom of the page. As of today, it costs $14.00 per day for cars or motorcycles, $15.00 per day for campers, trailers and RV's, and $18.00 for a bus or tractor trailer. Once you've paid at one park, you don't have to pay again that day. If you change parks, just show the parking Cast Member your dated receipt. From the toll plaza, follow the signs and/or Cast Members to your parking spot. Note your location (I usually take a picture with my phone), catch a tram, hit the park, and have fun! Have a Magical vacation!
