This is really annoying, but I don't think it'll be as complicated/confusing as people expect it to be.
Then again, I've never needed to use tickets 5+ days after I first entered a park without tickets lasting that long.
Six Flags has date based tickets and so do other parks. I'm more upset about price increases than I am about HOW those price increases are happening. I don't have a big issue with the idea of multi-day date based prices.
....For now. Let's see how I feel when it actually happens and how messed up it is.
My FP day is the first week of October. I AM glad it's before
MDE inevitably has another magical enhancement when they flip the switch to make this go live.
