Does the Wyndham Hotel at 4 th and arch have special parking rates for events held there?

They don't have any special rates, they do have parking right next to the hotel but even if you're staying at their hotel you'll need to pay for parking. The rate is $38 for a whole day. Or $12, first hour and then $10/hr.

Not sure sorry.

Yes i believe so

I know if u are staying there the rate is cheaper. Not sure about special evenys

I'm knot sure
