For the rest of September, the price of a 3 Pier passport has been reduced to $30. On the final Sunday in September, the price will be only $18. The Piers are open Fridays from 6pm until 11pm, Saturdays from 12pm until 11pm, and Sundays from 12pm until 6pm. If you consider they have over 90 rides, that is quite a bargain.
