I grew up in Reno and LOVE Tahoe. If your daughter has any brains she will want to stay there. The snow in the winter gets a little annoying but as long as the roads aren't closed you can always drive an hour and find somewhere without snow. There are some amazing people who live in Tahoe too. The area you are talking about is a mix of condos - such as the Tahoe Keys as well as lower income housing - but still nice. I agree roadie gal - any woman should always be cautious though. Living in Reno - I would say Tahoe is safer by far. Of course, Reno is also safer than Oakland etc. So it's all relative.
The casinos would be pretty close to her.
