Each summer, the area of Central Park that is the Wollman Ice Rink during the winter becomes the Victorian Gardens, with a selection of amusement park rides and classic carnival games. Although all the rides can handle both adults and children, most are designed for kids between the ages of 2 and 12.
With this deal from Travel Zoo, you get park admission and unlimited ride wristbands for two on any weekday from August 16 through September 6, 2013.
The regular full price for admission and ride tickets on weekdays is $7.00 for park admission and $14.00 for an unlimited ride wristband ($21.00 total). You can also pay for rides as you go, at $3 a ride. See the Victorian Gardens at Wollman Rink in Central Park website for details.
