Excellent point. Of course, that's easy for me to say since I've enjoyed everything from the dearly departed Sovereign class to the Oasis class. But even those who are adamantly against the "floating theme parks" can't argue with the numbers. The megaships are selling like crazy, for top dollar.
Personally, I haven't tried the Icon because I focus on bang for the buck, and consequently I never sail on the latest & greatest. Which also means I probably won't sail on this new class until they're a few years old. But there are things I love about every class of ship I've tried, and I expect that to continue as I eventually explore the new ones. 🙂
