As an IHG member, I try to stay in their group of hotels. Because of this, I stayed here recently on a trip to Lansing, though it was not the most conveniently located hotel for my needs. It was my first trip to Lansing, and it's actually very easy to get around the city, so the location worked out just fine.
The staff was friendly; more importantly, the room was clean, comfortable, and very quiet. As someone else noted, the alarm clock was bright; I too covered it up with a pillow (I used my phone as my alarm). Unlike most other places I've stayed, the pool/whirlpool area is open 24 hours. And, the Crowne Plaza has toiletries that smell divine. I would definitely stay here again.
