There are many ways to parse the data. One way would be to add up "ride hours" instead of park hours. That is, add up the total number of hours that were cut on each ride at the MK, then add up the total hours that were added to each attraction at AK and you will get an entirely different result. And that is precisely why the crowd here is about 75% in opposition to the idea that the added hours at AK are a fair offset for the lost hours at the MK. Distill this down to its base level. If Park A has 60 attractions that each lost two hours per day, that would be 120 ride hours lost per day. Multiply that by 30 days and that would be 3,600 lost ride hours. If Park B added 4 hours per day for the month, but only had 10 attractions that took advantage of those added hours, that would be 40 added ride hours per day, or 1,200 added ride hours for the month. If you look only at how the turnstiles operated, you would see that Park A lost 2 hours per day for 30 days, for a total of 60 lost hours for the month. Park B gained four hours per day for 30 days, or 120 added hours. So the owner of the Parks has graciously bestowed upon us a net of 60 hours for the month. Yeay!!! But did the customer win or lose? Did the customer gain any dollar value for their ticket?
This accounting does not even attempt to account for the intangible of "ride popularity". It assumes that all rides and attractions are valued equally. But once you add in a multiplier for the fact that Park A's rides and attractions are valued more highly than Park B's, (assuming that is the case), then the disparity becomes even greater. (Conversely, if the rides and attractions at Park B far outshine the popularity of Park A's, then the lost ride hours might level things out.) Another example. If Disney reversed course and kept the MK open until midnight each day and in turn closed AK at 5:00 each day, the reaction might be one of resounding joy. But if Disney then announced that the only rides and attractions that would remain open from 10:00 until midnight were going to be the Hall of Presidents and Stitch, people might fight to get the extra hours added back to AK.
So you see, total hours only tell a part of the story. You have to factor in what rides, attractions and entertainment people are gaining versus losing. And it is very clear here that people feel as if they are losing a lot more by having the MK close earlier than last year than they are gaining by having AK open later than last year. Disney could keep AK open 24/7/365 and it would not make up for the lost hours at the MK. It really is that simple.
