Universal should beat Disney on a percentage basis in Orlando for 2014, thanks to Diagon Alley. They probably will to a lesser extent in 2015 as well, because DA didn't open until early summer. In contrast, WDW didn't open anything of note in 2014 other than 7DMT, and it is cool, but not DA cool. The rest of New Fantasyland was all the way back in 2012!
But the claim that many of the FP+ critics are making is that FP+ will drive people away. Hasn't happened.
I'm thinking 2015 should be a fairly interesting year for comparison purposes, because other than the spring break season for Diagon Alley, none of the Orlando-area parks have anything that's new. Kong isn't supposed to open until 2016, and IIRC the Pandoraverse is '17.
But, WDW is finally spending real money. If you've been in AK lately, you can see they are pouring a lot of money into that park to create more infrastructure, etc.. Not just the Pandoraverse, but an extended Africa, the new Africa-Asia corridor, a greatly expanded hub, and the show around the waterways. MK's hub expansion doesn't seem like much, but it will make a big difference for fireworks and parades. And, it sounds like Studios might get not one but two major expansions and a complete re-working. It took them long enough to react to the huge attendance boost that Potter v1.0 gave Universal, but the sleeping giant has awakened.
It's a great time to be an Orlando theme parks fan. Now if only Sea World can figure out what the heck they are doing.
