Universal spent $2billion on building IOA and Citywalk - it didn't make a dent on Disney, infact, it brought more people to the Orlando area and increased Disney attendance. Potter, regardless of how good it is, will not impact Disney attendance. Unfortunately for Universal, their parks do not have the emotional connection, scale and depth that Disney has. A simple example is to just look at the live entertainment offerings. Take this weekend, Disney are running Wishes, Fantasmic, IllumiNations, Block Party Bash, SpectroMagic, Celebrate a Dream Come True, Jammin Jungle, and many other shows (not even counting Star Wars Weekends). These are major productions invlolving hundreds of cast. Universal have nothing, other than a couple of shows, and yet both Disney and Uni have same entry fee.
This weekend looks likely to rain, that means that practically all of IOA will be closed for large periods of the day.
You dont want to get wet or dont like rollercoasters at IOA? That leaves you with about 2 rides you can do.
I'm not anti Universal, and I like some of their attractions. However, there are some very clear reasons why Disney are miles ahead of Universal, which a alot of people just don't like to see.
There are many reasons why people go to Disney over Universal... To demonstrate this, I have made a diagram using text...
Cast Members > Team Members: Disney Cast Members are globally known as being the best of the best (most of the time). Universal Team Members are typically not looked at particularly highly...
Disney Live Entertainment > Universal Live Entertainment: Again, as already stated, Disney put's a lot of time and money into parades and fireworks shows. Not so much with Universal.
Disney Family Friendly Attractions > Universal Family Friendly Attractions: Disney has a whole bunch of really good family friendly rides and shows. Universal has maybe 3 or 4...
Disney Original Concepts > Universal Original Concepts: Disney has created several properties for the parks (i.e. Haunted Mansion, Jungle Cruise ex.). Universal...not so much. Except for Disaster (i.e. rethemed Earthquake) and the HRRR, I'm pretty sure everything is movie based.
Disney Thrill Rides < Universal Thrill Rides: Universal wins this one because they spend most of their budget putting together the most wiz-bang new technology into their thrill rides. Harry Potter and the Forbidden Journey is going to be their masterpiece that follows up such great rides as Revenge of the Mummy, Men In Black Alien Attack and Amazing Adventures of Spider-Man. Disney makes some good ones, but Universal does have better ones.
Disney Attention to Detail = Universal Attention to Detail: I'm gonna call stalemate on this one because Disney loves putting in little things into their attractions that the regular park guest wouldn't notice, but the hardcore fan would. Universal loves making their movie based attractions just like they would look from the movie and does a great job doing that.
Disney's Appeal to Younger Guests > Universal's Appeal to Younger Guests: Universal may have E.T., Jimmy Neutron and Shrek, but that can't compete with Disney's mass library of characters...
Disney's Appeal to Older Guests = Universal's Appeal to Older Guests: I'd love to give the edge to Universal here, but can't. Universal does have more that appeals to older guests, but Disney's nostalgic appeal has lasting value as well. I call tie here as well.
Overall Scores:
Disney 5 Universal 1 Ties 2
