Yikes. 6th Street on NYE.....No free parking anywhere after probably 3 PM. No free covers. 6th Street will be closed to vehicle traffic. Way different as there will be many more people than on a regular night. Cops everywhere, which is good because of the pickpockets and assorted other scum. Many many DUI, DWI, and drunk in public arrests. My advice is, if you can afford it, hire a car and driver to drop you off and pick you up.
Here s a helpful hint: Don t go.Sixth street, especially the bars and nightclubs on Sixth, amounts to one of the most-hyped, least interesting areas of Austin. ... But if you do go, go to the Ritz Theater (now known as the Alamo at the Ritz). (My family has a financial interest in it.)
