You're incorrect about hours, WeWork provides 24-hour access at your assigned office to all members except On-Demand members who pay per-day to acccess a WeWork location. Hot Desk, Dedicated Desk, Private Office all provide 24 hour access. Front Desk / Community Staff are usually present only during 9 - 5, but otherwise there's no difference between 11am on a Monday and 11pm on a Sunday -- I am typing this from my Dedicated Desk at 19:53.

You can see this information on the WeWork Plans page (https://www.wework.com/plans), and you can see events listed after 5pm at the WeWork Irvine location, demonstrating it is not an outlier and is definitely open after 5pm.
