I booked in April 2017 for Anthem in May 2018. I have an inside cabin on deck 10. I just called on Sunday after seeing lower prices and I saved over $500 on my cabin. I was amazed. This will be my 15th cruise (10th on RCCL) but this is my best adjustment ever. The rep told me it was because of Price Integrity going into effect. I am one happy cruiser now.
