Fast Lane Plus online - sold out?

"Hi I need a little more information.... .... Anyhow, I didn't understand the difference between FL and FL plus (which is already SOLD OUT online for every weekend in July) but now it's starting to make sense......"

Has anyone experienced that they sell out online weeks in advance?

We might preorder the passes for the 3rd or 2nd of July a few days before to check the weather, but now we are a little bit concerned about the availability...

It makes sense to limit(put a number of only so many that can be sold online) the online sales of fast lane plus so that patrons have them available to purchase at the park.

I've always though it was too risky to purchase them in advance because you never know 100% how the weather and crowds will be. That said, I've never noticed them sold out online before. I've only ever seen them sell out twice in park. If your in the park before early afternoon, you'll be fine if you decide you want to buy them.
