Since your ds is going off to college, this is a great time to start new traditions (hey, they have to start sometime!).
It sounds like it's a good thing your ds will drive to his grandparents, as he may want to cut the trip short. :glare: I would definitely give your ds "permission" to do so. (I put that in quotes because, after all, he is now an adult and can make his own decisions).
FWIW this year may be the hardest - just like when friends went off to brick and mortar kindergarten, after everybody adjusts to the "new normal" things seem to be fine.
