I had a chance to walk through some of the PATH on Thursday last week (only south of King Street) for a dentist appointment. It was still about the same 20 to 30% of the normal population walking around which I saw back in January. The increase in activity has stalled there. The food courts did have a few more businesses open, but otherwise many retail shops remained closed, or open with reduced hours. I went to take in some clothes for alterations where I always used to go and found it was open only 9-1 (and I got there at 1:20!).
It was announced where I work that the Return to Office has been pushed back slightly again to May. I'm not sure why they did that, but I've heard from friends at other businesses their planned March 1 return was also pushed back to April or May too.
