Last week, my plane was delayed and I didn't get in until midnight. Uber and Lyft were both at least $55 when I looked, so I gave up and used Mears Connect instead. But I was alone, so the $16 for Mears was much better than $55 for a rideshare.
BTW, if you haven't been in Terminal C yet, be prepared to do a great deal of walking. The place is vast and there's no moving walkway. Also, I don't know how it's working now since I did carry-on only for this flight, but in December, I waited an hour for my checked bag to appear.
