The ratio always prioritizes LL, as it should. DAS is already accounted for in LL allotment and guests redeeming late or at the same time are still guests that were included in the original LL allotment. That doesn't mean there is more demand for the attraction. But yes, this will temporarily increase the ratio of LL and cause standby lines to temporarily increase. So what’s your point? This has nothing to do with encouraging additional LL sales. And generally the original LL backup decreases the perceived value for those who have purchased it.
Amazing how you’re talking out of both sides of your mouth. (It’s not increased demand for the attraction but a temporary increase in the number of people wanting to utilize the attraction.)
How do you figure they came up with each attraction specific admittance ratio?
Do you think that they just randomly picked a number? Or did they analyze the usage and determined an admittance ratio which insured a maximum wait time in the standby queue under normal operating circumstances and average attraction demand? What do you bet that number was just enough to make the lightning lane option look very attractive.
