Bummer, hotel deal wasn't as good as I hoped. Anyway it's a bit less than the con rate.
Use the website hhonors/thankyou, save 30% off the overflow Hilton Garden Inn that is next door (so $115 instead of $125). The nights before and after con are only $80, which is pretty good.
BTW link works around the country for big discounts anywhere you might be going from Dec 14-Jan 7 so feel free to share. :P
