That's true to a point...The problem is that there will be another economic downturn at some point and Disney is not going to be able to discount enough to make up for it and wont be able to cut staff without further lowering service quality. they are playing on the bubble and that isn't encouraging when looking ahead when the parks wont be able to carry the financial burden of the company any longer.
You seem to look at things in a very tight timeframe, which is fine for a quick investment and sale, but as a long term investment, this looks very ugly. In the past, ESPN was able to carry the parks through 2001 and 2008, but that simply is not the case anymore. The parks, Star Wars and Marvel are basically the entire company right now...without one of those pillars, Disney looks really stagnant and iffy.
