I know that it came from insiders, but I would caution Universal strongly against a fourth “dry” theme park. Three theme parks, and two water parks, sound like the sweet spot: enough to get guests for a three or four day weekend (3-day tickets used only on dry parks), but enough to sell someone on a week stay (5-day ticket, visiting three theme parks and two water parks). That’s an easy marketing message to communicate for selling vacation packages.
I also say this, because I don’t want new additions to be spread as thin as they are for the Disney Parks. WDW has a tough time balancing four parks, and despite their current slate of projects, DAK is not getting any major additions any time soon after Pandora opened. With the Universal “One Attraction a Year” concept, I would not want to see a 3-or-4-year gap between major installations at any given UO park, even if the “UO Resort” as a whole would receive something every year. And that’s assuming that they’d stick to that formula, or that it would that same pattern they’ve been working with for a few years now.
We know there’s a new theme park, and a water park seems very likely given the large number of hotel rooms coming, but I’d rather see Universal expand Hollywood and to more international locations, than worry about a potential sixth park in Orlando.
