ExcitedCruiser

So I'm a first time RCI cruiser, have been on Carnival about 5 or 6 times. So I am quite confused of the price guarantee part for RCI. My fiancé and I are going to try RCI on the Oasis of the Seas for our Honeymoon in late May. She purchased the tickets and paid in full back in November / December. I happened to go on to RCL after seeing an ad pop up on my facebook news feed about their current sale. I pulled up our purchase price which is ~$2900 for our tickets, which includes a superior balcony state room. I pulled up the same cruise with the current sale, and not only is it over $500 less right now, but it included $100 on board credit. I tried to find some info about how, if there is any chance, we'd be able to either recoup some of the difference back or at least as a credit of some sort. RCI's site only talks about 48hrs after a reservation....I pulled up some old posts on this site that talk about paid in full, 90 day penalty time etc, but those were from 2014 and I'm not sure how the current policy has changed since then. Do we have any sort of case to bring up to RCI? How would we go about it? :o Thanks for any input! EDIT: So I went a head and called RCI, to see how they'd help me. He said we were still in time to get money back if it was less. He checked, said it was $99 less, plus a $100 on board credit. Better than nothing I guess, I'm still trying to see where $99 came from though.
