The short answer: yes. And they'll continue to do it until attendance begins to fall, which there are no signs of happening anytime in the near future. There's already pent up demand from the pandemic. They've got the 50th anniversary coming up. That will last 18 months, ending just in time to celebrate the 40th anniversary of EPCOT. According to their most recent earnings call, WDW turned a profit even at reduced capacity. So, yes, they will continue to charge a premium for less services until there's a revolt.
Me personally, I'm going in September. I had originally planned 4 nights/5 days at WDW at Coronado Springs. They've ticked me off to the point I cancelled my reservations last week and am reducing my time at the Mouse House. I saved so much money, I'm able to extend my trip by a day. So, instead of giving The Mouse all of my money, I've reduced my Disney days from 5 to 3 (not to mention cancelling my CS reservations) and spending 3 days at Universal. I also sent their customer relations an email telling them exactly that and explaining why. To be quite honest, I'm more excited about Universal than I am Disney.
If they see more of that, they might change their policies. Until then, they're going to continue to charge more for less.
