The answer is not to trim the park going experience. Okay, so they don't have to add new attractions - I'm good with that. But the cuts to the parks in terms of service/entertainment/acts/venues/dining, etc. are a cop-out. So would be canning front-line CMs.
They're doing one good thing though already, and that is booting management glut. Those are the kind of cuts that need to be made. Cuts outside of the parks. Trim down all TDO corporate staff. Shutter a resort or two. Halt all DVC development across the board. As a last resort, if attendance continues downward, implement the rolling park closure plan (for example, 1 water park open daily during weekdays, DAK & DHS each closed 2 weekdays). Is it better to go to a more crowded park that is offering full service for the same price you've been paying, or to have your choice of 4 "parks lite"?
IF THEY LEAVE EVERYTHING BETWEEN THE GATES ALONE, THEY WILL RIDE OUT THE STORM. Cuts inside the gates only crap all over your brand and admit that you want to crap all over your customers, by making them cover your backside.
Do car companies start leaving parts out on the assembly line when sales are down? Do surgeons only clean out half the clogged arteries if the network stock tumbles? Does a garbage collector only pick up half your trash when he loses 1/3 of his customers to cheaper competition?
On a side note, anyone know how Adventures by Disney is doing? If attendance at the resorts is down (when a family can do it for under 2 grand), I can't imagine AbD is doing great a 3-5 grand per person. Not that I don't think it's a great product, I would love to do it someday.
