Sure, it is a cheap and easy cost cutting move, but one I don't blame them for using.
Not that is wouldn't be nice to have both running but it is so far down the line for most people that it is kind of funny we are even having this discussion. Disney is now giving days away to the water parks so few people go. It isn't just Disney either. Water parks in general, at least in North America, have low attendance levels.
Bottom line, there are a TON of other things Disney could do to engender some good will or reverse course that will have a far larger impact than this.
