To make the most of your time in Kansas City, it's recommended to rent a car or use ride-sharing services like Uber or Lyft. Some historic sites are within walking distance of each other, but others will require a short drive. Expect to spend around $80-100 for two days of car rental or $50-70 on ride-sharing services.
If you have more time, consider visiting the Kemper Museum of Contemporary Art or taking a scenic drive through the Missouri countryside. If you have less time, prioritize the National World War I Museum and the Nelson-Atkins Museum of Art. Skip the Boulevard Brewery if you're not a beer fan and opt for another local landmark or restaurant instead.
