Personally i think the skyplex is going to become a strength for universal.
This is what i think about that,
1) This addition is going to draw more people into this northern part of the i-4.
So i think Skyplex will help to draw people from the Disney "Area" to the Universal "area"
2) The skyplex isn't a full day theme park, so it could become a step into a Universal trip or vice-versa ! (and again, center the activity into this part of i-4).
3) The visitors attracted by this kind of thrilling attractions will love to ride those two themes parks. So, buy ticket for both of them $$$.
4) Imagine yourself, (for the most courageous of us), onto the top of skyplex 3 second before you dropping, with a spectacular view on universal, What a great commercial for Uni !
And to finish with that, in his future development, if comcast manage intelligently his additions, he could profit, i'm pretty sure, from every aspect of skyplex !
And of course, this addition is going to motivate comcast to propose us a Wonderful CityWalk 2.0 in the future !! Je croise les doigts !
So !! This is my personal opinion, what are you thinking about ?
