I don't get all the hate for the JP island only having one arch. It still has the other... and it has an arch on the ride that the boat goes through. Jurassic Park is my favorite film of all time. I have original movie posters for all 4 films in my home, framed. I even created an entire website devoted to dinosaurs and covering the JW films. And yet, losing one of two arches does not bother me. Not in the slightest.
Now if they ever bulldozed the Discover Center, I'd weep openly, for a week.
If anything, I was more sad to see the "electric" perimeter fencing with the blue/red lights go away along that strip of walkway than I was the arch. But with the addition of Raptor Encounter we got all new fences with lights, so I'm all good now. Plus, Camp Jurassic has the best stuff for a JP nerd like me. The tower is themed like the raptor pit tower in JP. The fences and gates between areas are themed like the interior electric gates in the film (like when Nedry's escaping.) And the ambient sounds and fog are incredible. I could spend hours in Camp Jurassic.
While waiting for Kong softs today I spent a good deal of time wandering around the caves of Camp Jurassic, enjoying the atmosphere. All that is the magic stuff I would be sad to see go. We still got another arch. No need to be upset. That's my thoughts anyway.
