Looking to carpool to the Novel Marketing Conference

I’m flying into Austin for the Novel Marketing Conference in January and I did not rent a car. I will if I need to, but I want to see if I hitch a ride first.

My flight arrives in Austin at 1:40pm.

I need to leave the hotel for the airport no later than 4:30am Sunday morning. (Yeah, early.)

Anybody else happen to have a car and driving to and from the airport around those times?
