Secret ?: Secret Thing That You Must Do Before Vacation

Put a hold on the delivery of your mail, or ask someone to collect it for you (same goes for any packages that might be coming your way)
Put a hold on the delivery of your newspapers
Arrange pet sitter or kennel stay
Pay bills
Check toiletry/gear/clothes supply — buy new items as needed
Load up on reading material — buy magazines and books, check out books from library, download books on Kindle/iPad
Order and pick-up a refill on your medication if it’ll run out while you’re on your trip
Let friends and family know about travel itinerary
Arrange for a ride to the airport, or reserve a parking spot (if your airport is big enough for that to be needed — not the case here in Tulsa!)

Throw away perishable food items from fridge, as well as any fruit/veggies that might go bad while you’re away
Notify alarm company that you’ll be away
Get all laundry done (including bed sheets — nothing better than coming home to fresh sheets!)
Check-in for flight online and print off boarding passes
Print off driving directions (yeah, you can look these up on your phone, but there are plenty of times when your digital map of choice doesn’t work properly)
Write down/print off destination addresses
Check weather of destination
Confirm hotel reservations
Confirm rental car reservations
Program phone numbers you’ll need into phone
Download apps, music, and movies/shows for yourself and the kids
Set up email away message
Fully charge phone/tablet/laptop
Withdraw cash and change it for single dollar bills in case you need to tip shuttle drivers, skycaps, hotel valets, etc.
Call bank to let them know you’re traveling
Run the dishwasher
Pack everything (minus what you’ll be using on travel day) in your suitcase and carry-on bag

Note: If you have a very early flight, some of these things should be done the night before. Just grab a protein bar and head out the door.

Pack dopp kit after getting ready for the day
Make sure all doors and windows are shut and locked
Make sure the garbage disposable is clear of food scraps
Take out last bag of trash to garbage can
Wash any dishes you used for breakfast by hand and put away (really, protein bars are the way to go)
Turn off lights and turn on timer for lights
Unplug electronics
Water house plants
Set thermostat for away temperature (upper 70s in summer, upper 50s in winter — the rule of thumb is 4 degrees off of what your normal temperature is)
Close blinds and curtains
Double-check bags/clothing for loose ammunition
Be sure your EDC is TSA compliant; pack into suitcase the forbidden items that you normally carry on your person (pocket knife, gun, etc.)
Double check that you have IDs and itinerary packed in carry-on bag

Check for items you often use right up until leaving, and end up forgetting:

Diapers
Diaper disposal bags
Wipes
Snacks
Books (way, way more than you might think you’ll need — they’ll go through ‘em quick)
Small toys
Bottle/cup with built-in straw (sucking will help pop their ears)
Benadryl and/or Tylenol (see here for proper dosing)
Toddler headphones
Tablet with downloaded movies/shows
