While I agree with an earlier reviewer that the The Domes' neighborhood can be rough, it is not so problematic that you should avoid this diamond. Normal common-sense is all that is needed: don't leave valuables in view, park near a light pole and near the entrance. I have visited The Domes many times with no problems, though as a woman I am always aware of my surroundings.
I heartily suggest that you visit The Domes for their special Music Under Glass events, when the exhibits are open at night with live music in the common area. I was completely surprised at how different each dome looked and felt in the dark compared to my earlier daytime visits! Beautiful, mysterious, serene...Completely fantastic event that you do not want to miss! A light show set to music is performed at specific times in the Show Dome during the Music Under Glass events, and is absolutely magical! A wintery nod to Milwaukee's wonderful summer fireworks shows!
