As I said at the beginning of this thread, this concept doesn't bother me at all and doesn't come as a surprise because different pricing for different dates and different times is so common in the entertainment industry (note Universal's pricing for Express Passes). What I do care about is how the pricing translates into actual dollars and how any increases compare to the usual increases that Disney has implemented for decades...
The biggest thing that jumps out at me from the Touring Plans article is that the sample price chart he uses is very dramatically different than the one shown earlier in this thread. In that chart from WDW Magic, the bronze price seemed to be about like current prices, silver was a little higher, and gold was a little higher than that. But all of the examples continued the current structure of extra days costing $10 after the first 4 days. In that chart, a 10 day gold ticket was $405. In the chart in the Touring Plans article, that same 10 day ticket is listed at $732.
It would appear that different people are seeing different proposed price charts. I don't know exactly where the point would be that price increases would significantly affect how often we would visit WDW. The chart from WDW Magic wouldn't really faze me, but the one from TP definitely would. There is a big difference between what I can afford and what I am willing to pay.
