K.,
As far as the trip goes, unfortunately I don't have much advise, but leaving at night is right on track.
Last year, both my husband and I lost out fathers to lung cancer. One in August and one just a few days before Chrstmas. He needs to treasure every minute. Look past all of the medical equipment, treatments and medication. Talk about old memories, things they would have liked to do together, things they never said to each other that they wanted too. Remind him now is now a time to be a "strong man". Let his feelings out and tell is his dad everything in his heart. Do whatever his dad wants to to sped his time. If he wants to play golf, take him to the driving range even if he is in a wheel chair. The last memries will be ones that will last forever. They are as more for him than for his dad. I will pray for your family. LOts of luck on the drive and hopefully the trip will be memorable.
