It is one exit past Hilliard, but I would recommend the Staybridge Suites, off the Tuttle Crossing exit.
The hotel is a great business hotel, and you should be able to negotiate a rate close to $110-120 for a single room. They also have some unique suites, with two and three bedrooms feeding into a common room.
The hotel also offers a substantial breakfast and during the week has substantial eats out during happy hour. (Not snacks, an actual meal!) Plus, there are a good number of decent restaurants, plus Tuttle Mall, in the immediate area.
Ask for Polly, who is the group booking manager.
It is right off the outerbelt, so it is a quick trip down to Berliner.
