No Google maps show's both highways the same in time to travel

On my two car trips today my little man didn't scream as much so that was a bonus, just when the car stopped did he get upset again and didn't take him as long to settle... so things might not be as bad as I first though... although knowing my luck....

I was hoping to try and do it without stopping over night but will have my iPhone with me so I can book in somewhere if need be, the reason for this is if both boys sleep better over night then it's best to travel then, however if I need to pull over for a nap I will.

I've got some formula sticks just in case but might give him a formula feed sometime before now and then to ensure that he drinks it... fussing over it mid travel doesn't seem like much fun...

We hire our car so I've talked to the car hire company to get a bigger car for the trip, unfortunately the one they first suggested isn't available next week but they have a Chrysler Voyager which I'm hoping to pick up this weekend so I can drive it a bit before we take off.

So I'm thinking the current plan is to leave here Tuesday early evening.... or first fed on Wednesday
