Efficiency isn't a priority for most museum visitors, but sometimes you're on a really tight schedule yet still want to see all the museum has to offer, so it becomes important to view the exhibits efficiently.
Luckily, Nick Gray of Museum Hacks has come up with a clever and ultra-efficient way to visit a museum, keep walking and still take in all the exhibits- and it all starts when you grab a map.
Nick's method in a nutshell- grab a map, then keep walking through the entire museum without stopping to read text on first lap.
Take a break and plan your strategy for re-entry, go back in and explore the exhibits at your own pace, spending time on the exhibits you care to learn more about, and you've now seen it all- twice!
