A couple things:
1) Lots of people like to stay at the hotel that the convention is actually being held at, not another hotel down the road or even a mile away. So you should probably inform people what hotel you're planning on staying at.
2) Have you seen our hotel page yet? We have a group rate and it's definitely cheaper than $160/night. If you're paying that much I don't understand why you wouldn't want to stay at the hotel that the convention is at.
