Universal Cineplex - 20 Screen State Of The Art Movie Theater
Take your pick of the first-run movies in one of our 20 theaters featuring wall to wall screens, state of the art projection and digital sound, and stadium-style seating with high backed rocking chairs. Box office opens at 12:30. Matinee shows before 6:00. Free Parking After 6pm & an $8.00 Concession Rebate with Paid Parking Before 6pm!
My only question is if I park at 9:00 a.m. will they honor it if I go when the park closes?
