For suites I'd agree that X tends to be more expensive than others. However, if you compare say balcony rooms these three lines are close. I looked at a balcony/veranda room on each of the above trips, 2 people, middle deck cabins, each one with "all-in" package (tips, drinks, wifi) and taxes and came up with total price for 2 passengers:
Celebrity @ $4,076
Princess @ $4,078
HAL @ $4,838
So saying that Celebrity is being killed in prices as a "across the board" statement is not fair. Saying they are overpricing their suites is a fair statement, one I would agree with, & one that is frustrating me to no end and forcing me to look elsewhere.
