is city walk still open after 10pm? or that is when the rides close down?

Rides closed after 10 PM, but in Halloween Horror Nights, they stay open up until 7 AM.

Check the website. You'll also find out about special events.

The park is open until 9pm during the holidays, summer, and some weekend nights. The website will always have current hours posted. City Walk is open, but they enforce the 18 and younger curfew at 10pm.

Rides close down on 7pm, and yeah stores somewhere between 10pm - 11pm
