Everyone's already mentioned some great things. The Steamship is the Arabia, I've done it twice with family and enjoyed both times. Oak Park mall is actually right off the corner of 95th street and Quivera in Overland Park - about a half mile off of I-35 to the east at the 95th street exit. There is also great shopping at The Legends off 435 and State Street. They've got the hot spots nailed if your looking action, Power and Light district and Country Club Plaza. If you're looking for something a little more romatic and low key one of my favorites is Wines by Jennifer in Parkville (Wines by Jennifer - A Global Wine Boutique) just north of Downtown. A husband and wife travel the world tasting and buying wine, they feature a different "flight" for tasting each month for $8 pp and offer some light snacks as well to pair if you like. Wine for purchase as well. Hope you enjoy your stay!
