I am taking my Dad on the Grand Princess on October 29 from Venice to Rome. Right now we have a mini-suite. Because of some favorable financial circumstances, I am thinking of making it so we each have our own room or we upgrade to a suite. I checked availability and there are a fair number of both still available.
Is there a certain time when it will be significantly more advantageous to discuss this with Princess. I am happy to pay extra, but don't want to throw money away if the prices will drop or if we can get an upsell or upgrade at greatly reduced cost.
