Again.. Far to tied up with my use of the word "entitlement". I said "Yes, it is slightly different, but that in no way means that you should be entitled to return whenever you want" meaning that just because you cannot see the return time of each ride no matter where you are, that shouldn't mean the inconvenience of not knowing should allow you to return whenever you wish. Subsequently, I added that the system is a perk, or bonus, not something you have to use, so its not like not always knowing every ride's return time makes it an unfair one. Feel free to use adjectives such as "allowed", or "free to" in place of "entitled" in order to calm your fixation.
Basically, agreement != what they have been practicing for years.
Also noteworthy is that the practice in question has nothing to do with "the way the disney guys programmed it to work." The program is made to work with the return time and estimates and return times are still calculated and printed.
