My Father-in-Law goes to Wildacres, up the mountain from Little Switzerland, a couple of times a year to teach gemstone classes and it is an awesomely beautiful part of America. Lucky you for getting to be there all the time.
When my BFF and I travel anywhere we schedule stops. You can find parks, recreational areas, elementary schools with playgrounds, etc...kids have to get up and move around. It will be much more fun for everyone if you just figure much more time for travel and plan at about every 2 hours you are going to have to stop and have a snack or meal, bathroom time, and scheduled play time for running around acting wild.
If it were me and I was going to travel 10 hours away I would schedule my trip like this:
Leave the night before I was expected to be anywhere. Leave a couple of hours before bedtime for the little one, lets say they go to bed around 9pm. I would leave around 6-7 pm after having a really good dinner. They may fall asleep but they may be so excited the just vibrate with it.
Maybe around Columbia, before playground closing time, I would plan a late snack at McDonalds, you can always have yogurt parfeits or apple dippers along with whatever else you think is appropriate, the purpose is to run around and play. Then after letting the little ones play for a good 30 minutes load up and travel for another 2 hours or so, they will fall asleep with full tummies for the night. Plan a stay in a hotel so everyone can have a good nights rest. Maybe Savannah, it's about half way to Miami, 320 miles. You have reached about half way and had dinner, a play/snack break, a child got to sleep, and a couple more hours of drive time out of the way.
Get up in the morning and have a good breakfast, if you drive to Jacksonville Florida it's only about 2-3 hours, should be mid-morning or nearly lunch time, and you can eat, have play time, and we usually figure this will also be "big" potty time. The extra running around after eating 2 big meals should cause them to need to evacuate their bowels. Then
drive on towards your destination. From Jacksonville all the way to Miami it's only 5 1/2 hours. I don't know where you are heading along the coast so I figured the fartherest but it can still be broken up into 2 hour sections.
When we traveled before my BFF's van got wrecked we had a built in DVD player that used the stereo system in the van, it was awesome. She would put a DVD in and put the sound on the back speakers and the kids didn't even notice us. Now we have 2 DVd players, they are her kids players, each player has two jacks for headphones so the kids can double up for the movies playing. The boys usually have something they like in one DVD player and the girls almost always have in a Barbie movie in theirs. The kids range from a 3 year old boy to two girls age 6 then a 9 year old boy. Her kids don't have tv and only get to watch movies,mine have cable and see all the latest shows.so, when we travel we try to get a variety of movies from either house. The kids usually pick them so we know they are ones they like.
We pack coolers with a variety of drinks like juice boxes and small milks, grapes, individual size fruit cups, yogurts, carrots strips cut very thin (the baby carrots are okay if she is older), cheese cubes, etc...that way if we stop at a park we are prepared food wise for snacks. We also have a box of non-fridge snacks. If she is younger you don't want her eating dry stuff and getting strangled, we usually had pretzels, chips of various kinds, and some things they think of as candy like granola bars, Little Debbie snacks or Hostess are good too.
