O.K so it looks like this trip is actually going to come together!
Our two older DD's have backed out - they can't get time off from work

. It will be just myself, DH and DD8, we are thinking of driving straight through.
Our trip dates are 8/26 - 9/2 and we will be leaving from Monmouth Co. NJ (exit 109 on the NJ parkway). According to map quest it will take just over 17 hours to get there.
What do all of you experienced round-trip drivers think of leaving on Thursday 8/25 around dinner time (5:00pm?)? Our thinking is that DD will fall asleep around 10:00 and hopefully sleep through the night, DH will sleep for a good part of the day on Thursday and take the first part of the drive, I have to work untill 2:00pm so I will take a nap in the car and pick up the second part of the drive around 4:00am and stop for breakfast around 8:00am.
Tell me what you think of this plan, will it work or are we making a hugh mistake that I'm not aware of?
Help, please!!!
