Not only is the difference in price substantially more than the NRD, but the prices for the NRD are quite high as well. I expected prices to go up after the cruise industry was shut down and impacted due to COVID, but these prices are crazy high. And with all of the cutbacks in service, it's making cruising less desirable. We just can't justify committing $900 non refundable dollars for a $4500 cruise over two years away. I'll take the advice of some on this thread and check out Princess or Holland America. Otherwise, we will have to look into other vacation options I guess.
