First and Foremost, Pack Dual Purpose Items
Examples include:
Toilet paper doubles as tissue paper in a pinch
Beach towels are, of course, great at the beach and they double as a throw blanket on a cooler evening as well as for the road trip
Olive, coconut or vegetable oil; butter or margarine. There's no need to bring every kind of oil/spread you own
Aluminum foil functions for both hot or cold applications, plastic only functions for cold uses
All-purpose seasonings: blend equal parts granulated onion and garlic instead of one container of each; bring one meat rub, specialty or all-purpose seasoning, not all of the individual ingredients to create your own spice blends while away
Animal crackers and dry cereal such as Cheerios double as snacks for you and your pet
Rice/Pasta: Long or quick cooking rice, not both. Pasta should be limited to one or two types that you consume most often
Beverages: Focus on the essentials such as coffee and purified water. If necessary, fill in with tea bags, lemonade mix or a two liter of soda
Wine/Beer/Liquor: Narrow it down to the basics such as one wine, beer and liquor, not the entire bar and every kind of mixer in your pantry
Mentally Walk Yourself Through a Typical Day and Evening
Examples include what you will wear from head to toe by time of the day:
Early Morning: Attire for taking the dog out, coffee on the patio
Morning: Breakfast at your place or in the highway hotel's common area
Mid-day: Work, shopping, errands, lunch, exercise, appointments, social or other activities
Late Afternoon: Beach or pool attire, sports wear, hobbies, exercise/hiking, work/online video calls, etc
Evening: Dinner at your favorite upscale or casual restaurant, nightlife, or just lounging around on your sofa for tv night
Bedtime: Sleepwear and everything needed for a good night's rest such as a robe and slippers, night creams and an eye mask
Don't overlook the items that accompany your attire:
Accessories: Belts, jewelry, purses, scarves, bags, canvas totes, etc
Hats: Sun hats, baseball hats, fashion hats and winter hats for the road trip to/from your destination
Jackets: Casual jackets such as windbreakers and lighter weight zip-up jackets as well as a trench coat for an evening out and cold weather jackets for the road trip
Bulk, Big Ticket and Seldom Used Items
Examples include expensive items such as computers and electronics and travel-sized portions of bulk items
Vitamins and over the counter (OTC) wellness items purchased in bulk such as vitamins, supplements, energy/nutrition/fitness products, etc.
Vision: prescription eyewear, contacts, eye drops, sunglasses
Hearing: hearing aids, Q-tips, ear-related products
Rx items that may be seldom or occasionally used: aspirin, cough drops/cough syrup, tissues, cold/flu remedies, medications, etc
Jewelry: wedding rings, bracelets, earrings, necklaces, every day and special occasion pieces
Electronics: Electronics are such an integral part of our lives, there's a lot of components to remember to pack. Cables, connectors, computers, mini towers, monitors, printers (+ink and paper), surge protectors, the list is extensive.
Hobbies: Pickleball, golf, tennis, hiking, photography, picnics, etc. Whatever your thing is, don't forget to pack everything necessary to set up in your warm weather destination
Cash/Credit Cards/Checks: Although money is not a big ticket item, cash is king when traveling. You'll need to have plenty in small to large denominations for tips when on the road, cash-only vendors, parking and tolls and much more.
