2. Phone Numbers
Who actually knows phone numbers anymore? I literally cannot even tell you my husband’s number right now; I always just use voice dial. But if you lose your phone or it runs out of battery while your party is separated, you’ll wish you still had those 90’s era memorization skills. To thwart this kind of disaster, write the pertinent phone number on a bandaid and stick it under your clothing. This is a great idea for children too, so that a cast member can quickly contact you if they get lost.
