I am planning on visiting Denver, CO in July 2014. While I am there, I am planning on visiting 16th street; denver art museum, and other downtown attractions. I am planning on staying at the Hyatt downtown. Can you let me know if the downtown area is safe. I would not be renting a car, so I am wondering if I would be able to get to these sights by walking. I would also like any feedback or tips on vacationing in Denver during the summer. My son who is 15 years will be travelling with me. Thanks.
