This may be the only exception to allowing a little junk in your trunk.

Let’s face it, kids like junk food.  So why not splurge a little bit more in that category while on the road?  After all, it is a vacation.

But be careful not to leave out healthy foods altogether, or you’ll have to work extra hard at redeeming yourselves when you get home.  Try mixing the two together: chocolate covered peanuts, yogurt with M&M’s, or celery sticks with peanut butter.  Don’t forget to pack a few apples, because the old adage, “an apple a day keeps the dentist away,” comes in handy when the toothbrush is at the bottom of the suitcase.

New and interesting toys

Before leaving for the trip go to the dollar store and “splurge” on toys that you know your children will like.  You can surprise them in the car with their new toys as soon as they start to get restless.

Try mini board games, mazes, or coloring books.  The best part is, you won’t feel guilty (and they won’t miss them) if you accidentally donate them to charity when you get home.

But don’t forget to let them pack a few of their favorite toys from home, too.  Let them fill their back pack with anything they like, provided it’s not the pet turtle.

Portable games and DVD players can be expensive, but if you plan on having more road trips in the future it’s well worth the added expense.  Just remember to get headphones, unless you want to be able to quote the entire Shrek movie by the time you get home.

Make frequent stops

Do your research before leaving to find unique places that your children will enjoy seeing along the way.  Check out www.roadsideamerica.com for offbeat tourist attractions.

If you’re stopping at a hotel overnight, consider one that has amenities such as a pool, playground, game courts, or nearby recreational activities like laser tag or miniature golf.

If they’re old enough, give them a little spending cash.  The kids will feel more independent (and thus happier) if they can make their own choices on what to purchase.

Plan ahead

Map out all directions before hitting the road to avoid getting lost.  Pack only necessary gear and make sure you’re well equipped on the road for accidental spills or other potential surprises.  Make a list and check it twice before leaving.

Stay calm

Your children will react to your own emotional well being, so try and relax.  Stay calm during sibling rivalries and laugh a lot (especially if you get lost).  The positive energy will set the tone of the trip and will make it a lot easier for everyone.
