I prefer for Universal to avoid the market entirely. Unless they have some sort of new & fresh concept, I just don't see the interest. RCL is well established and is on fire right now, just announced another Perfect Day area in Mexico. Disney does well since they have a large a fandom to draw from, which Universal doesn't really have. Norwegian & Carnival are doing just fine, I doubt they need Universal.
I'd love to be wrong, but the only thing Universal can do on a ship differently is a HHN house and a Butterbeer bar lol
I'd rather they stick to concepts like Kids & HHN, I think that's an untapped market they can dominate.
