I just registered for Techshow yesterday. As Jeff Beard points out in LawTech Guru today, February 26 is the last day for "early bird" registration and the $100 discount that comes with it. However, if you miss the deadline, try calling (800)888-8300, extension 5909, and mention priority code TS100 to get the "early bird" discount until March 12. I got this info in a flyer from the ABA yesterday, so this should work. ABA Law Practice Management members get an additioanl $100 bucks off, for a total conference cost of $595.00.
Also, if you are going, don't use the Sheraton downtown to stay. Get on Hotwire and search for Chicago hotels in the North Michigan Avenue/Water Tower Place or Magnificant Mile/Wacker Drive areas and your hotel will be no more than a $4.00 cab ride from the conference site. I got the 4.5 star Swissotel across from the Sheraton for $103 per night. At last check, ABA's "discounted" hotel rates for the Sheraton were $177 per night!
UPDATE: Just got this tip: Go here and enter your arrival and departure dates and you should get the Sheraton for $129.00 per night. Thanks, Patricia Joyce.
