Directions to the hotel from the airport:
We have reserved a block of 30 rooms at the DoubleTree Suites by Hilton Hotel, for the dates of May 11 (check-in) through May 16 (check-out). The address is 303 W 15th St, Austin, TX 78701 (the corner of 15th and Lavaca), which is about half a mile from where most of SALT will take place.
Please use this personalized reservation page to access our group rates:
You can also make a reservation over the phone; call 800-222-8733 and mention the group code "SLT".
The special rate ($200 / night) block offer expired at 1 AM on April 14th, 2016.
For other lodging options and more information about Austin, see Local Information.
Wikitravel has a page on UT and nearby attractions.
For now, please see the NASSLLI 2012 - Food page for a listing of restaurants / cafés near campus. (I'll try to do a full update before SALT starts.)
The UT Parking system has two garages that are near the CLA (Thursday) and very near EAS (Friday-Sunday): the Conference Center garage and the Brazos garage. Their parking rates are hourly, with a maximum of $18 / day.
There are private parking lots near / on campus that are cheaper, if not as close or predictable.
Due to the central location of the UT campus, you will have to venture about a mile out to find free street parking (I'd recommend looking just east of I-35), and then walk or bus over, but I know of some people who do that.
