Checking luggage at the port of san francisco pier

I remember from our cruise out of Fort Lauderdale, FL that we dropped off our luggage with the longshoremen to be put in the bins and then onto the ship.

What about dropping off our luggage at the pier in San Francisco?

Does it work the same way...giving our bags to a longshoreman along with a tip ($5/ bag)...and then they arrive at our stateroom on the ship later in the evening of our first night at sea?

Any advice or suggestions specifically about dropping off luggage at the pier in San Francisco that any of you might have would be appreciated.

It works the same way at San Francisco. Only difference is that it is smaller and you will have one or maybe two ships in port.
