I know a lot of brits who used to do 2 week Disney holidays who now do a 10 day 4 day split. Add in the water park and a plethora of new attractions and this will probably not only increase the amount of days people spend at uni but also increase the amount of people doing so, recent annual pass increases could also work in Uni's favour.
I just spent 14 days at uni and didn't set foot on Disney property even though I'm an AP holder, probably my last Disney annual pass I hasten to add.
Will be interesting in the coming years to see how the dynamic changes but I do worry about crowding, if they don't/can't expand their offerings whilst dramatically increasing hotels then we could end up with a similar problem that Disney has and see huge price increase after price increase to try and keep the crowds at bay, although for very different reasons.
I genuinely think if the upturn continues at such a staggering pace then a third get will turn from a pipe dream into a must, although avatar, star wars and toy story could indeed swing the pendulum once more.
exciting times ahead in theme park land.
