Off their web site, we booked a Park, Stay, Fly package with what I believe was 14 days of Parking included. It was a great deal and the facility was much nicer than we had expected. Both of the rooms were very large and would be able to serve a family of four. Morning breakfast was good. Since we were arriving late we made a decision to stay overnight on our return from Europe too and drive to Corpus early the next morning.
The Quality Inn (Choice) web page often has special promotions so check them out before booking.
Drawbacks include that it is a small hotel and a bit further from IAH than most of the other airport hotels. As a result, the frequency and wait for the airport shuttle is bit longer than ideal, but still doable.
Also, the hotel parking lot is not fenced in. If I had a super expensive car or other car that might be a likely target of thieves, I might not feel 100% comfortable to have it parked here for a long period. This is Houston, and I would have this same concern at most other parking options too.More
