I think you should first visit
Legoland California before declaring it's going to be a "tipping point". I've been to
Legoland California several times over the past decade, most recently in summer '08. See my previous post on how that park is poorly operated, although it does have its positives....
Legoland California is a custom built park on a gorgeous plot of lushly landscaped land in the hills just above the Carlsbad beaches in northern San Diego County.
It's a 50 or 60 minute (depending how legally you drive) easy freeway shot straight down Interstate 5 from Disneyland. It's in a master-planned development with easy access to 12 lanes of modern freeway. It's been there for 10 years, and has had steady investment development and plenty of additions since opening. It's a fully fleshed out theme park with 30+ attractions big and small, with a new SeaLife Aquarium that just opened attached to the main park. An attached water park is under construction there now, not yet reflected on the park map.

There are lots of new mid-range and upscale hotels and time share condos directly adjacent or very close to the park, with plenty of stylish restaurants and an upscale mall at the bottom of the hill along the beach. Heck, there's even an
In N' Out Burger nearby too.
And even with all that going for it, it hasn't
done a thing to the Disneyland Resort in the last decade. It's very rarely mentioned in theme park circles in SoCal or on Disneyland boards. It's pretty much just a regional theme park for San Diego County and South Orange County, plus a few tourists who have a child heavy into a Lego phase take a day out of their week in SoCal to visit.
I would imagine that
Legoland Florida,
only after a full decade of development and additions, would slot into that same position. When
Legoland Florida is more established and expanded a few years after it opens, I would think it might pick off some folks with a rental car who would otherwise go to Sea World or Islands of Adventure for one day of their Orlando visit.
Considering all that, and the performance of the California park, I can't imagine
Legoland Florida is going to impact
Walt Disney World in any meaningful or noticeable way.
