As a newly solo traveler, I booked two cruises to Mexico departing from San Diego. For the cost of a 4-day in October (Sapphire Princess) that I cancelled, I was able to book two cruises, one 5-day cruise and a 7-day cruise on the Diamond Princess, both for the same cost of the 4-day cruise. Not only were the cruises sharply discounted, but no solo supplement either. Everyone, make sure to check the Princess website! Because of the very low fares, I doubt that TAs will be discounting those anyway. Total cost for the two cruises: $600. Yes, I added the Princess Plus package to both cruises, which brought the cost up, but still a smoking hot deal.
