My son and my daughter-in-law to be asked me tonight to make their wedding cake. I am thrilled. Here is the catch...the wedding is about 9 hours from my home.
The wedding is outdoors in August in N Idaho. I am assuming that fondant will not only travel better (by car) but will also hold up better with the outdoor weather? Is this true?
Also, anyone that has traveled that far with a cake by car have any suggestions (besides don't do it).

Hi Joanne, first of all Congratulations with your sons wedding and absolutely great that they asked you to make the cake!!
My experience with fondant is that it holds very well, except for very humid climates (or days 
). Just make sure that you ice your cakes with a stable BC before covering with fondant. I would transport them all seperately in cardboard cakebox and stack them there at the event. If you are having airco in your car, it really wont be a problem for so many hours.
For cakes covered in BC i have no experience, we don´t do that over here in Holland, only fondant and marzipan covering.
Goodluck with all the preps!! 
Also congrats to your son.
Do you have to travel. I was wondering if you baked the cakes ahead of time and possibly took the stuff to make it with you. Is there a possibility that you could make the cake at your sons house then take it where they are having the wedding.

My first thought was go early and decorate it there. Good luck and Congrats to your son!
Make sure you AC is working... 
And try to stay calm. I drove 17 hours with a competition cake (which is much sturdier than a normal cake), and every time I hit a bump or had to slow down rapidly (darn semi trucks pulling out in front of me), I had a little stroke. I wanted to get out and check it every 5 minutes. lol!
Ditto on what Brandisbakes said. August can be hot here. I have AC in my home and my car and at work. Maybe even put them in coolers if you can on the way up and keep them cool up until you have to set them up. Ask if there will be some shade so that the sun is not melting it. Good Luck and Congrats!!
PS don't forget to post your pics later.
I did a wedding cake for a competition and drove it 12 hours (was supposed to be 9....but that's what happens sometimes!). My suggestions are to put each layer in a box and set up there (like someone else said), make sure you have sufficient dowels in the layers, and try not to stress too much over it!
The cake I did was 16, 14 & 10 (stacked, on 5" push in pillars), and 6" (on 7" push in pillars). I transported it there in seperate boxes except the 14" and 10" - they were stacked and in one box. It made it there fine. I was lazy and transported the whole thing home all put together. It took 9 hours to get home (driving approx 80-85). Miraculously it made it home with very little damage!
