You are trying to manipulate data to support your claim here. Those are the per person prices that don't account for taxes, fees, and gratuities on package components, all of which will change depending on what promotion is offered. Bottom line is that once you cross the 110 day line, the same upgrade options aren't available anymore, and before you ask, yes I in fact HAVE talked to Norwegian about upgrades inside the 110 day timeframe and what others are saying here is 100% correct. Once you are inside that timeframe the promotional offers change, which means you cannot do what you are looking to. I am sorry you don't like the answers you are getting, but they are in fact correct.
