I'm looking for the same thing, but more in the $160 range. Try more zones and if you get something be sure to post it.
The calendar feature is great. Although it did point out that I didn't get the lowest rate for the weekend. :)
I bid $122 and they made a counter offer of $137 so I took it.
I've stayed there, its a great hotel in a great location.
I think if you bid a little smarter you can get cheaper for this weekend.
Used the Savings Barn link.
