"And organise them by groups like attractions and activities and food."
Jessica also recommended people add important transportation hubs like airports or train stations so you know how close they are.
Travellers can also search the internet for the best places to visit or stay and compare them to your map, she added at the end of the video.
Having a map in front of you wasn't just helpful for directions but also for planning your itinerary for the day, as you can see what attractions are close.
"Another really great thing about this is you can more easily plan days," she added.
"This is also really helpful because sometimes you just wander, you explore, you deviate from the itinerary but you can pull this map up at any time just to see where you are close to."

"Are you kidding I've been doing this on regular Google Maps and giving myself a hard time for nothing!" another added.
One traveller also added their own recommendation: "Pro tip – download the map so you can pull it up OFFLINE and are never lost in the city you're in."
