YES! My kids love these. They even sell souvenir books where you can store the pennies. The machines are everywhere in both parks. You will find them at most of the rides and even scattered around at various shops. The choices of pennies you can press vary depending on where the machine is located
For example...There is one located in the store where you exit Spiderman at IOA. There is also a quarter machine there. You have 4 choices of Spiderman pennies on the machine. There are other Marvel characters available at other machines on the Island. At the Cat in the Hat, the choices are Seuss characters. At Jimmy Neutron, there is of course Jimmy and Spongebob. Near Jaws at US, the choices are Jaws related. There are many, many of these machines. I will have to find my kids' books and see what all they have. In addition to the ones I already mentioned, I know they have some for MIB, BTTF, Terminator, Hulk, Jurassic Park, The Grinch ( I LOVE THE GRINCH!)... I am sure there are many more that I just can't think of.
