4. I suck at directions, so if you’re traveling anywhere new — especially to a foreign country or a place where you won’t have Wi-Fi — pre-save some key searches (like your hotel’s address) into the free Google Maps app before you leave. This way you can access a real-time, overhead map of where you are, and it’ll point you in the right direction, even without Wi-Fi. This genuinely saved me from getting lost soooo many times.
