There is a lot of stuff to do on the east and west sides, actually mainly just shopping. All the fun stuff is generally downtown. Also try to go in early may for the annual Wichita River Festival. If you like groups of 100,000 people or more than you will really like the parade and fireworks.
Fondest memory: I was born and raised here
If at all possible schedule your trip for some time in May when the city has it's Riverfest. There will be even more than ever to see and do. There will be arts, crafts, performances, and bed races near the river and Century II. The Wichita Convention and Visitors Bureau can tell you more about that. 1-800-288-9424.
Fondest memory: Have many fond memories of Wichita. Watching the bed races is fun. The zoo is great. Spent an entire day just visiting the museums in town and still did not see them all.
