Hi Stephanie!
A big CONGRATULATIONS on taking your first trip to Walt Disney World! Having taken many long car trips with my five children,I have learned several tricks along the way to keep the kiddos entertained and my sanity at the same time.
Place each of your children's name on a gallon size Ziploc bag and fill with coloring sheets, crayons,stickers, activity books and any other surprises.I don't let my children see these activity bags ahead of time and they look forward to seeing the surprises in the activity bags.
Here are some great car games and you can inexpensive prizes before your trip at local dollar type stores:
-Disney Alphabet Game- A round robin of the alphabet, take turns going around thinking of every Disney character that starts with each letter of the alphabet.
-Travel Scavenger Hunt- Include this sheet in with the activity bags.Make a list of easy to spot and not so easy to spot items you might see on the road during your travel time.For little ones who cannot read yet, instead of putting words just add pictures.
-Make your own I-Spy container and give each child a list of all the items in the container.
-A rousing game of "Name that Tune," gives away to lots of giggles on car long trips.Call out a name when you pause the song letting them know they have to finish the lyric.I recommend using Disney soundtracks (of course) and other easy recognizable songs so all the children have a chance.
To keep down the never ending chorus of "Are We There Yet?", give each of your children boarding passes or travel tickets.For every half hour of travel time that has gone by, take each one of your children's tickets or stamp their boarding pass.This is a great way to give them a better sense of how much time is actually left on your journey, especially if you have a smaller child.
Best Wishes!
