While I can see the points being made here, I have a tendency to look at both sides of the coin. Of course, as a consumer I certainly feel the pinch of price increases when it comes to housing, gas, groceries, ac/heat, car insurance (I wish all those bad drivers would stay out of central FL ha, ha.)
However, I think the price increases are fairly well alligned with other economic factors and I would rather spend $21 per day for a full day at a Disney park as opposed to close to $15-20 for a couple hours of entertainment at a movie. Realistically, I know that accounting for food and extras it really is more than $21 per day, but I still think it's pretty reasonable.
It's a matter of planning well and researching to get the best deal for your family. A vacation is an "investment" and not going to be "cheap" when it is a highly popular vacation destination. I think that it has become more affordable for lower to middle income families since MYW was introduced and value resorts were offered as far as vacations are concerned. For some, it may be a "once in a lifetime" trip, but at least it's a less costly one due to those changes I've mentioned.
Just my take on it.
