PSA: If you're a childless adult looking for nightlife, Icon ain't for you.
Just got back from a week aboard Icon; I've also been on Harmony and Symphony before. Here's the thing: Icon is an incredible ship. They made a lot of spectacular additions and updates and fixed a lot of weird design flaws, and there is just SO much to see and do. But...the nightlife ain't it.
I'm 30F and my sister is 35; both of us are unmarried and childless. We're not, like, clubbers or anything, but we like to have a drink and hit up a silent disco, yaknow? We went on Symphony two years ago and had an absolute blast with the nightlife: the gameshows (which weren't overrun by children), the pub (shoutout to my bae Jamie Ray), the silent discos (always our favorite!), the late night DJ at the Attic, the Club RED experience in the ice rink, so on and so forth.
Icon was bizarrely dead of all that. There seemed to be almost no one in our demographic--it was all boomers, teens with their families, or young married couples with babies who didn't go out. (I'm gonna take a wild guess and say the pricing is what shut our age group out...) The music hall was so cool, but completely dead. Our favorite spot was the Dueling Pianos bar (shoutout to James and Janelle!) but the crowds were mostly boomers who only wanted to hear, like, Sweet Caroline, and sat there stone-faced when she played anything more modern than 2000.
If going out to a lively night scene is a key factor in your vacation goals, don't do Icon. At least not until the prices drop, so maybe other millennials can afford it lol.
(Edit: also, they haven't updated their music database in at least 2 years. We didn't hear a single Chappell Roan or even Sabrina Carpenter song. I mean, sheesh.)
