How far from sesame place to seaworld in pennsylvania?

Although we have no Sea World, there is the Adventure Aquarium on the Jersey side of the Delaware River, across from Center City. There is a ferry that takes you across (no cars). I'm guessing when I say that it would take you about a half an hour to get from Sesame Place to the ferry by car. Then you have to find a parking spot at Penns Landing, and then you have to wait for the next ferry. Or you can go across the Ben Franklyn Bridge to get there. I truly don't know the timing.
