As far as I can tell the Icon of the Seas is basically fine; even on the environmental front (important!) I see no reason to believe it's worse per passenger than other ships.

A lot of opposition to it feels like elite snobbery against middle / upper-middle-class people.

Any good anti-Icon arguments I'm missing?

something people don't consider about environmental impact is the splurge—"My 25-room mansion is eco friendly so I'm eco friendly."

even if you're using econfriendly methods in your gigantic non-essential-thing (mansion,vegas casino,mega cruise...), your splurge footprint (resources, labor, land) is not eco friendly

and i say this as a someone who thinks environmental impact is a very secondary factor when judging human endeavours 

i just find the 'splurge' contradiction in the people who care quite striking

More people per boat = Less waste per person
