http://www.servicedogs.org/dogwalk09/ We would like to attend, I'm probably going to start the search for a dog friendly hotel soon. Is anyone else planning to attend?
Update 2/18/09: Link fixed, sometimes the hyperlinks act strangely - sorry guys.
Update 2/24/09: I did a google maps search for "dog friendly hotels austin texas" and there are pet friendly hotels very close. I included the closest few in a reasonable price range. If you want a really upscale hotel there are lots of those, but I'm not sure if they accept pets.
-Homestead Studio Suites Hotels
One pet is accepted per guest room. The general manager has the authority to allow additional pets per room, based on his or her own discretion. Guests with a pet will be charged upon check-in a fee of $25 per day, up to a maximum of $150. http://www.homesteadhotels.com/hotels/austin-downtown-town-lake.html
Oh man that looks like fun, especially because it's to break the Guinness World Record! We'll really try to make it out! Thanks for the info. Oh and the link didn't work for me either. So I'll paste a different one here...
