Why, do you want to reenact this scene?

I mean, we have taken measures to prevent dumb mistakes... But their reaction won´t be that much different...
Well there is first of all the obvious cool factor of having the heroes come in and check out the improved Park and get their reaction. Don't know if Tim and Lex are going to come along for the ride but if their parents still get a divorce then I guess a weekend with Cool Uncle Elliot would be a convenient place to dump them while things are hashed out.
As for how things will go in the meeting, I think it will be more of a calm is slightly spirited debate than the argument and dire warnings of OTL. Alan and Ellie would probably be a lot more receptive to us from the spot because they are dealing with a Zoologist and veterenarian who respects the dinosaurs as living creatures who need to live as close to their original environment as possible than John's way of treating them as theme park attractions, book and film. Any questions and concerns they have like pack behavior or diet can be easily addressed here with Elliot having looked into such stuff from day one and he's not going to dismiss stuff like the raptor's intelligence, which for Alan at least was the biggest red flag. It's not going to be perfect, but it's as close to perfect as they can get and Alan and Ellie's first reaction was that of pure joy and wonder to Jurassic Park. It was tempered by the showmanship and arrogance that followed.
As for Ian, he'll probably still be a sourpuss but he would at least respect Elliot here for knowing he is fallible and never once being lax in the creation and operations of Jurassic Park instead of John resting on his laurels and assuming it was an end all be all. Ian's Chaos instincts were probably going crazy seeing expenses cut in the human element, everything reliant on a single computer program and only the electric fences acting as defense. Here with a large staff, multiple fail safes and programs and proactive management tempers chaos theory greatly.
