I am a Celebrity cruiser (22 cruises with them) and I tried Royal last November. I did not care for it at all. Some passengers told me this specific cruise was a bit unusual, not as nice as to what they were used to. I found the food and service was the huge difference in the lines. I also choose a very large ship and found the ship too big with too many passengers. I expected to meet more people etc but the ship was too large to see the same people. For me, I would not go back to Royal again. I will be curious to hear what your experience will be if you try Royal.
