My current pass expires in a few days....and I just bought TWO premium passes. One to activate when Springfield opens, and one that I have to activate by December so that I can have an annual pass when Wizarding World opens. Yeah, I'll have two annual passes valid at the same time for a few months, essentially "losing" a few months, but at least I just locked in the $179 Premium Pass price for me to see Wizarding World AND avoid future price and parking increase! If you can afford it, I recommend everyone do that, at least with a No Black Out Dates pass
I'd recommend to do it soon. With Disney raising their price today, Universal should be following in a bit.
