Yes.Will I be able to pickup my rental car and drive it back to pick up my son who will be watching the luggage?

If it's just the two of you going together would simplify things.Yes. Or just have son and luggage ride rental car shuttle with you.
I have read reports of people having long waits for rental cars after the cruise. I don't know if that's unusual or common. If you wouldn't be comfortable leaving your son alone at the port for an hour (or more), I personally would plan to take him and the luggage on the shuttle. If he's an adult... he may opt to wait. It could be a short wait, it may be longer.
Enjoy your cruise!
I would suggest this as well. Sometimes those shuttles can take quite some time.Yes. Or just have son and luggage ride rental car shuttle with you.
