Bring the smart phone app to a museum. Your visit will be much better for it. I visited the Georgia Aquarium and was able to listen to fascinating narration at almost every stop in every exhibit. Similar apps are available for major museums, providing you with interesting comments, tours, and restroom guides, all rolled into one app. Check it out before you leave to speed up the download process.
