PLAN YOUR TRIP TOGETHER
Don't designate the scheduling to a single person, otherwise that individual (OK, it's usually Dad) will get blamed for everything the family didn't like about their vacation. Day-long visit to the beer museum, anyone? I'm a big fan of Microsoft's OneNote. Not only can you use it on your home computer or iPad, it allows you to share documents, maps, itineraries and spreadsheets with the whole family. Believe me, you'll avoid lots of complaining down the road.
