Thanks for the help. I think the plan will be as follows: Park the car Friday on the street in the UWS where the party will end Sat., and stay in one of the Ws Fri. night.

I am a savant at finding street parking in NYC. Plus I drive a MINI, which makes its own parking space. I was never intending to park in a garage, so I realize now that my OP made it sound like I wanted a hotel with a cheap garage. I meant a hotel located on/near streets with noncommercial parking. I hate garages almost as much as I hate taxis. It's street parking and subway/foot for me.
