I always do that flying into LAX. Then I just catch the transfer at the airport nice and early the next morning. The only hiccup is that they keep a separate list of people without a flight time, so you just tell them you flew in the previous day. Personally, though, if flying into SFO I'd just take the BART subway to the Embarcadero and walk, Uber, or take the waterfront streetcar to the cruise terminal, instead of sitting in traffic with a bus full of unmasked people. It also allows you to stay at a non-airport hotel and get some sightseeing time in SF.
