Draw people away from what?
If its drawing people away from MK, its not all that big a deal, and in fact i would lean towards Mattpeto's statement it doesn't matter. If people are spending money for tickets at MK, and instead are "drawn away" to AK, there no net gain for WDW. Its the same money spent, just at a different park. If the argument is that you can get current WDW guests to spend MORE days in Orlando but expanding DHS or AK and making them a bigger draw, then you have something. Or if you think that by expanding them you are drawing people away from other non WDW parks, then again you have something. But theres no value to just spreading out the internal WDW guests and better/more equally distributing them across the 4 parks.
