Always bring a map
Tip #1 - Always bring a map
You can never rely on your phone for anything, you might not get signal, or something may break. It’s always handy to have a physical copy of a map tucked away for quick access and use.
I like to use Google Maps to make a custom map with all the attractions from my list. I usually print a zoomed out version and a zoomed in version, printed front & back. This way, if my phone dies, I have a hard copy.
