..the title says it all

About my SIM (a residential one), i'm close to a kind of termination of the preparatory work (the terraforming, landscaping, waves, sounds...and so on)
Just wonder if the GRAND OPENING process is very clear ... or if it doesn't have to be... ?
I meant, is there a kind of rule ?
- Better to make the grand opening day before any residents are installed ?
- Better to make the grand opening day after all residents are installed ?
- Can be done even if .. let's say.. half of the residents are about to live here
Or everyhting is good as long as you do it with care ?
Just wondering... ,-)
nota: if you know good singers/artists of any kind/ and so on, drop me a line here or in-world, i culd be interested
