Shipping our Suitcase to San Francisco

So, my suitcase is too big and heavy to go with us on AMTRAK...so I am shipping it out to San Francisco via a delivery service.  It will be waiting for us at our hotel when we get out there.  We have lots of warm clothes to take because, hey...it's Alaska...and you need rain gear, fleece, and lots of other stuff to layer because the weather is so unpredictable.  That's why we had to get a whopper suitcase.
