There are 13 of us driving to WDW in October from Michigan. There will be 7 of us in one van. I rented a van for 10 full days with taxes and unlimited miles and it came out to $488 (from Budget and I have one about 8 miles from my home). I know that sounds like a lot of money, but if you figure how much 7 plane tickets would have cost us (around $1,800) it is very reasonable even with the price of gasoline (about $500). We are splitting the cost between 2 families too! Since we never drive while on property, we were looking at renting 24 hours one way, dropping the van off, then re-renting one for the 24 hours back. It was only $50 cheaper that way. We usually get there in 19-20 hours, but you never know how weather or accidents or construction can put you behind. Just in case we don't make it in 24 hours, we can at least breath easy knowing that the rental will not be late. And, we will have transportation while onsite just in case we need it. I was able to use a special code through my employer and a random discount I found online. I haven't seen anything that good since.
