I know (but still can't believe) no uber or lyft in Austin. Do I need to rent a car for a 4 day vacation? Hotel's not set, but will be downtown. 4s-fine points, Hyatt Regency-points+cash, Hilton- points or pay are my tops, but am open for other ideas. Plan is relaxation and bar hopping, eating good food, etc. We have family there so will see them one day and I'm sure they'll come pick us up if we don't have a car.
