I am trying to convince DH to take a June trip to WDW. We live in Indianapolis, and for our first trip in 2009, we flew. The only way I will even get him to think of this trip is if we drive down 
We have 3 kids who will be ages 7, almost 5, and 20 months at the time, and I am toying with the idea of going straight through at night to make it as easy on them (and consequently us!) as possible. It's about 15 hours, so I was thinking we could leave around 4 or 5 and get there by 9 am. I'm worried that the kids will be crazy hyped up, we'll be exhausted, and we'll start our trip off poorly. I'm also concerned because my boys are in booster seats and they seem horribly uncomfortable to sleep in.
But I am would love to hear thoughts from those who have done it (if you liked it or you didn't) about how it was, how tired you are when you get there, tips, etc. What time did you leave? Were you able to get a nap the next day, even with kids?
Anyone?
