At the gate they will direct you. Have fun.

Ask the car rental place for a map or the car or your phone should have GPS mapping

There are lots of signs. Enter off Ball Road.

Just map to Disney and then you will see signs for parking you can pick the 1st one you see as they will shuttle you to the park both parks are right by each other.
