It's been announced that in 2020 the Carnival Miracle will do cruises out of San Francisco. Might have to try it out if the price is right. The Grand Princess is here but I don't bother looking at if for cruises anymore since the prices are jacked up. Cheaper for me to go to San Pedro or Seattle and cruise out of those ports, even with airfare. Will be interesting to see if that same thing happens with the Carnival Miracle.
