I'm assuming you want to be near BIAV, which is the only Orthodox weekday minyan in town. Your best bet is probably the Overland Park Convention Center area, which has at least one Marriott option and also a Holiday Inn and is less than a 10 minute drive to shul. The entire area though is very suburban and safe, so if you find a different property with a better redemption, you should be fine.
If you're going to be there over Shabbos, it's a long walk from any hotel, with the closest well over a mile away from either BIAV or Torah Learning Center (Chabad, down the block from BIAV). But if you don't mind the distance, the walk is very safe.
