Okay, folks, we've got the Wineconf hotel set up now.
The key is to call the hotel directly and ask for the Wineconf rate; we have a reduced rate of $99/night for the weekend. After the weekend, the price will jump, so if you wish to stay more than a few days, you may want to shop around a bit.
Note for non US residents - $99 is the price without tax, so the total price will likely be 10% or so higher after the taxes are added.
I've updated the Wiki page, and Andrew Balfour added some travel info. The Hotel phone number is 1-612-332-6800.
Cheers,
Jeremy
