You have to presume that the people who crunch the numbers at Disney have figured that there is going to be capped park attendance for the forseeable future (which means into 2022) and concluded that they can make more money from their domestic market in that case.
Our next trip is planned for August 2022. Our plan was to do what we did on our last two trips in 2017 & 2018. 6 days onsite, hitting the parks early, back to the hotels during the middle of the day, and then back to the parks in the evenings. Then 2 weeks in a villa, with the 14-day Disney ticket being used in the first week at the villa (building in some much-needed rest days). The 2nd week in the villa is day trips & a couple of days at Universal.
Now, without the free dining plan, without Fast Passes, without the Magical Disney Express, without the Extra Magic Hours, it just doesn't make sense for us to stay onsite anymore. So we're doing 3 weeks in the villa. That means instead of us staying in a Disney hotel for 6 nights and spending 11-12 days of the first two weeks in the parks, with all the spending that entails, we're going to spend 0 nights in a Disney hotel and spend, at a push, 8-9 days in the parks.
But the drop in the amount of money Disney get from my pocket will likely be replaced (and then some) by someone from their domestic market. Our overall budget will be the same, we'll just spend it elsewhere. Maybe a 3rd day at Universal and try out their water park, or maybe take a couple of those days we're not going to the parks and head to Miami for a couple of days or something. Maybe take that hot air balloon ride we kept mulling over on previous trips, but never got around to doing.
