As personal organizer Helena Alkhas says, “summer vacations require planning and organization.” Make notes on what you want to do and who’s coming along, then pick and research a destination. Make a folder of important documents — reservations, maps, passports, etc. — as you collect them. Then, figure out what to wear; some locales will require layers even in the warmest months. Finally, pack essentials such as prescription drugs, eyewear and power cords in your carry-on, just in case your luggage is lost or delayed.
