It also was a different time (the golden years). It is funny, there is one complaint about how busy the parks are and then next about the pricing. The first can't happen if the second is too high. As far as what some view as gouging and that "there are not other offers". They are wrong, unless you are a local (then you get discounts on tickets or can buy AP's that are an advantage to us that live out of town). If i remember correctly and you can have Mear's pick you up and drop you off for only the vehicle fee, also most of the offsite rental properties have buses that also deliver you to the park. The issue is you are bound by their schedule.
While this is a money grab to an extent, it also an interesting business plan. The increase in parking, will play a factor in a person's (family's) decision into staying on property. If you can justify staying on property when you include room, transportation, and PARKING, it makes staying on property a much better value. I have stayed off property twice, and after each trip I swore i would only stay on property in the future due to the hassles with staying off property. In both cases we were with another family that was trying to save pennies, but I think we ended up spending more due to cost of parking, trying to get back to your vehicle if you had park hopped, etc.
In the end, if it isn't affecting attendance, it is a good business decision. An yes attendance is down, but I truly believe, that is a function of Star Wars Land. For example we are not going to Disney World next spring, and instead are going on a Disney Cruise simply due to waiting on SWL.
