So it appears that 2nd St and Republic Square Park are the places to be tomorrow night.
For adults, the 2nd St District will be having a Sip.Shop.Sweet. event from 6pm-9pm. There will be drinks and eats, but also for every $100 you spend you will get an entry into a drawing for a stay at the new W. hotel and a mini shopping spree. If you were planning on doing some shopping at any of those shops, tomorrow's the time to do it!
For the young and young at heart, Austin Parks Foundation's movies in the park will be showing Rudolph the Red-Nosed Reindeer and How the Grinch Stole Christmas at Republic Square Park (at 4th and Guadalupe) starting at 7pm. Get all the detail here
