If they were smart, they would fast track a majoir refurb to start late in the Summer to next Spring or Summer. That would give people more an incentive to visit the lower lot when Potter opens. That would help balance things out. After all, next year will be the ride's 20th anniversary. Yes, you can argue that it wouldn't be wise becausae people would want to ride it after seeing the JW movie, but would you rather have that when it would be a pain next year when people will stay upstairs? Once Potter opens, they will have reached the point of no return and will need all the capacity they can get. This year would be a good time to get started on it, but we know that seems impractical.
Would they could do is maybe add an indoor themed queue, replace most of the dinosaurs with Garner Holt (T-Rex would have to stay but be readjusted som,ehow since it was a LOT of trouble to put in), fix the older effects, do a touch-up on the containment area and past, and then maybe add effects in the interior portion. I think if they really wanted to, they could get it done around Potter's opening.
I'm just typing this because I'm suffering from creativity from boredom. That, and the ride needs this desprately. It's just getting worse.
