Sorry, but this is not comprehensible. The cruise is paid for by FCC... But in order to have FCCs, you must have paid for a cruise, correct? So, in order not to pay the insurance, you are willing to lose the money you originally paid? Yes, there is an expiration date for the FCC and the cancel for no reason works only before you take the cruise. You're not going to know if you like anything until you board the ship and experience the cruise.
It appears that you don't want to pay for the insurance. That's fine, and it is a risk you take.
As far as the original question, we don't know what is going to happen in August, much less October. We have to wait to see if Princess extends the cruise with confidence policy.
