Is there any place close and decently priced to stay the night?

Yeah, the Hotel Indigo is awesome!!!!

Not that I can think of. If you use Air BNB, yes there are quite of few places that are reasonably priced.

We stayed outside of town it's alittle cheeper, with less noise

Try Priceline. There can be some great hotel deals on the area if you submit a bid...

Comfort Inn & Suites Kansas City for $104 a night. Just off I 35/ I 70 near the Arabia Museum.

there are hotels downtown but reasonable prices I'm not sure
