Thanks for all the replies and suggestion

I was thinking that it would work out if me and DH took turns driving/sleeping.
My plan once we arrive in WDW(hopefully around noon) and our room was ready we would take a long nap and hit MK for PM EMH. Or just hang out at the hotel or DTD.
I have a few questions?
1. Can we pull into a rest area/truck stop and get a few winks at the same time? Is this safe to do?
2.If we relize were far to tierd to go on can we find a hotel with room open in the middle of the night?
3.Are there gas stations open 24 hrs or should we find a few on our route before we leave?
4. I was estimating 3/4 hours to eat and take breaks along the way is this to much/little?
Thanks for all the help
