This is a valid point. The real issue as you stated is the park has been Gutted while we wait for construction to be finished. They have added temporary entertainment options and minor attractions to try to bridge the gap but it's just not enough to keep people happy and entertained for a full day. I haven't been to DHS in a little while now but from accounts here people are saying that the attractions that are closing early were empty at night. It's probably because the people left in the park are waiting for Fantasmic and/or people have hopped to other parks or went to Disney Springs for the evening (Pandora is supposed to be pretty nice at night). It's definitely not a full day park these days and I'm not sure any amount of temporary offerings would keep people there longer when the other parks offer better options. They could keep those attractions open until park close anyway but if the majority of guests aren't enjoying them at that time then you aren't really hurting very many guests by closing them early. I realize that the primary driver of these closings is cost cutting and in an ideal world they would offer a discount on the price of admission but we all know that would never happen. IMHO it's a much bigger deal that they are closing MK several hours earlier than most typical summer nights because that park is actually crowded and there's plenty of demand to keep the attractions open later.
Both are symptoms of the mindless drive 'To Improve Margins at the Parks' thats thing from last earnings call which sticks in my head in point of fact it makes my head vibrate like Wile E Coyote with his head stuck in a bell.
There are two ways to improve margin one is by cost cutting, MK closing at 10 during peak vacation season, GMR closure all the 'little' cuts which add ip. This is what TDO has chosen,
The other is increase top line revenue but that involves RISK in that initiatives/products fail.
I think the biggest problem is that Burbank is afraid of risk taking and even worse how to take both creative and calculated financial risk.
This explains everything from Gasparillas running out of snacks by 7pm (because manager will be dinged if unsold), Restaurants not taking walkups to purchasing IP's to the Stock Buybacks. Everything TWDC does has to be 'A sure thing' when that strategy fails things fail fast as management is paralyzed because suddenly all the choices involve risk which because of earlier avoidance behavior they are unable to evaluate properly.
The worst thing about the cost cutting mentality is it's not Iger and his henchmen chortling about how they are cutting back on what they are delivering,
Its become institutionalized and somewhere there is a team of data scientists creating algorithms to analyze everything and decide what can be cut today and pushing those orders to park operations.
I doubt very much if there is a strategic look at whats being cut more likely its algorithmic because it makes senior leadership feel 'data driven' and sciency.
