I think the Country Club area is your best place to stay. You can uber or lyft from there to specific places fairly easy. the TWA museum if I'm not mistaken is pretty much by the airport so that is perhaps something you would want to do before you go to your gate as it is near the airport (I think). I really enjoyed the Nelson Art Museum and loved Q 39 for lunch. You just can't go wrong there. Try to get reservations if you go on a busy time hoewever. Have a GREAT time@
