The motels near or just south of the KC International Airport will be closest to me. A couple of the closest (and lesser expensive) ones are:
Laquinta Inn & Suites at 6901 NW 83rd St, KCMO (816-587-6262), and
Super 8 at 6900 NW 83rd Terrace, KCMO (816-587-0808).
These are nice since they are a straight shot down Barry Road about 10 minutes from my place. They are also right across the street from Zona Roza - one of KC's best shopping districts with lots of good restaurants and specialty shops.
