I'm gonna be honest: I wouldn't mind if you bulldozed Parisian Courtyard and French Street, and made a theater space that could have Sing: Live and a new VIP dining environment.
Could help widen the space around DMMM and Pets a bit too, and it would give Universal a stage for flex use purpose. Plus, Sing 3 has been acknowledged to be in some form of development, so unless if Illumination is now the Barbie, Nintendo, and Gru show; I imagine we'll get Sing 3 by the end of the decade.
