One week later could be the pricing difference, esp. if around Easter? Usually, I find them similar prices. Like others said, there are TAs whose pricing beats RCI direct by a quite a bit. Princess pricing tends to be very similar on their website and via TA. We sail both lines frequently and like both. I view Princess as a step-up from older Royal ships for amenities, entertainment, food, and equal to older (newish) ships like Anthem. Haven't been on newest Royals yet. Enchanted would deliver a quality product, Royal will have a bit "funner" vibe and more active/sports offerings. With teens/young adults, we prefer Royal, but not for 50% more!
