I completely understand this. But the fact is, if everyone just knew the 120 rule, meaning they knew to book their next ride every 2 hours (so for 8am park opening wouldn't be until 10am) genie was vastly superior (once they got rid of the 7am rule)
Think of how it would be right now if you just had to pick ur first ride every day (along with buying any ILLs) 7 days in advance for your entire visit
There would be plenty of inventory, you'd have at least 2 rides booked in advance, you could sleep in and not have to pick ur day of ride until 10am but you'd also have the flexibility and availability of choosing wherever else you wanted b inventory wouldn't be eaten up and you would get to choose from almost the entire ride offerings.
