I would also say it's fine... only thing that may kill you is gas money.
That combo isn't much of a fuel econmy car.
Just make sure it doesn't overheat and your fine. I would do a oil change or make sure the oil is good. Run 94 and you should be fine. You most likely won't make that trip without stopping to grab something to eat, or washroom break so just let it sit for a few minutes when you stop to cool down if you notice it starts running hot.
Besh wishes for your trip!
