Yes, but only if your appointment is for 8am or earlier.
I just called Costco and ask them if they had overnight parking (I have a 5 AM delivery ) . I was told yes but after 2 PM, I could park for the next morning delivery
No overnight parking.
I do not think they have overnight parking inside the facility. There is always a line of trucks parked all the down the street on the north side of the building. There is no facilities obviously.
