Yes, it is a big arcade. Most of the games/attractions don't cost extra. But you do have to pay admission. If you have a PAP, that is included in your ticket. If you get an Ultimate Park Hopper (LOS) ticket, it is included in your ticket. If you get a Hopper Plus, you might be able to use one of the pluses for admission (not sure though). Otherwise you have to pay the general admission of about $25-30. We always have a PAP, so we don't have to worry about the separate admission.
