Hi there! There are LOTS of things for kids to do in Reno. The Little Gym (new location by Costco) has wonderful classes. My son LOVES them. The teachers are great, classes are fun, and the facility is neat and clean. There are pools around town with lessons (county pools, and private lessons). We went to Silver Bear Swim School (Double R area) and again, loved the classes and teachers. In the Plumgate Center (Plumb and Arlington) there is a pottery painting place (close to a Starbucks for you!). There were a fair amount of summer camps, etc. but I think they are coming to an end, as school is almost back in session. You may also want to check your local YMCA for programs for kids...That's all I can think of for now, but if I come up with more, I'll post again.
Have a great time!
