What to do with a bag for 3 hours in NYC?

I’m flying to NYC tomorrow for a few days, and unfortunately bringing a large rolling bag because I’m bringing a friend a bunch of clothes.

I’m staying with this friend, but he doesn’t get off work until 5pm. I get into the city around 1pm.

I could get keys from him and head out to his place and drop my bag, and let’s call that Plan A.

Anything else I can do with my bag? Think a hotel might hold it for me without a reservation?
