Make all reservations including the hotel, attractions and depending on the trip, dinner reservations. Plan for downtime in between activities especially when traveling with kids. Remember there is nothing wrong with using a day or two just to relax. If it is a short trip, a good way to include some downtime is to travel really early and ask for access to your hotel room early. If the room is not ready, the hotel can store your luggage while you and the family enjoy some downtime on the grounds, pool side or grabbing a bite to eat.
Make lists. I usually make a separate list for each member of the family. The list includes outfits for each day, shoes, undergarments and personal toiletries. Make a list for the car including easy access items, snacks, change of clothes for kids and electronics.
