I was on the 25th-29th cruise and I cannot remember the exact number but I believe it was around 3200 give or take. It felt lively for sure but, in general, I didn't feel overcrowded. There were times when lounges were packed (I think they ran out of electronic BINGO tablets at at least one of the sessions); Triton's Lounge was standing room only on the final karaoke session and it was physically hotter in that room than right outside the door because of it haha ( let me tell you that you could not MATCH the hype in the karaoke lounge that night lol). It was hard to get a good seat for drawing when it was held in the Keg and Compass and unfortunately they didn't have all of the TVs showing the same thing so that was a bit of a bummer. Plan on being to your event a bit early if you're picky about your spots!
