1. Photos
Of course you’re going to want to take lots of photos while you’re on vacation. But the most important photos may end up being the ones you take before you ever begin having fun. Snap a quick photo of all the members of your party in their park clothing first thing in the morning, especially children. If worse comes to worst and someone becomes separated from the group, you’ll have a up-to-date photo of the individual to show authorities. It’s also smart to take a photo of your parking row for reference. (Speaking from experience, it’s NO fun to search the lot for your car at the end of the day—my kids may even say it’s a “disaster”.)
