You also have to factor in the cost changes. When you look at the hard ticket parties, the overall picture does feel rather sinister.
In 2002, MVMCP cost $34/ticket.
For 2017, they range from $90 to $110.
So, the price has tripled.
Double the events. Triple the price.
THAT is the issue. It wasn't as big a deal back when they were so much cheaper. It was a lot easier for the proverbial "family of four" to budget $150 for a party. Now we are talking $400 for a single night in the MK.
And that isn't even mentioning the fact that the unique offerings as part of the party have been reduced so much, or how many more tickets they are selling, exponentially increasing the crowd levels (and the overall experience) enormously.
It's the same pattern we see over and over at WDW. Prices have skyrocketed past any semblance of reason. Offerings have at the very least stayed the same, or in many cases been systematically reduced. In the case of the parties specifically, impact on other guests has greatly increased, and the value of the events themselves, both perceived and empirically measurable, has reduced significantly.
Happy Holidays, WDW style...
