Because attendance is an indirect measure of how much Pain the public is willing to endure. There is a point where the rise in prices will cause a fall off in attendance as people just can't afford or justify the cost. True, profits may not suffer, but the number of people in the parks will drop. Disney is about profit, true, but there is a bit of diminishing return going on.
Disney’s smart enough to know when to pull back, as they did a few years ago when they eliminated parking fees at WDW and resort fees at DLR (although parking fees remain)). They’re also smart at discounting, whether it’s free dining, ticket specials (like the 3d/4d passes last year), targeted promotions, etc. Remember in the 2000s when they offered free admission on your birthday, and later for volunteering?
This forum fixates on the Disney Bubble, but most people stay and eat outside of it. Last summer, the most popular tickets were the 3D/4D park tickets from $89-$99.
You can get more hotel for your money in Orlando, same WDW, than anywhere else in the country. Even the golf/ water park resorts in the Phoenix area - which target winter travel and were sold at bargain rates the rest of the year - now cost more.
Last summer, a family of four could’ve stayed at a beautiful resort with elaborate pool, did the four day park ticket, budgeted $100/day for food and spent less than $4K. They could’ve shaved $1K off that price if they went with less hotel. In today’s world, that’s not unreasonable.
Meanwhile, I’ve been on these forums for two decades. Some of the same users saying they’re just about done with Disney.. have been saying that for years and are the first ones to insist that staying at a CL room in the Beach Club at nearly $1,500/ night is the only way to Disney.
