They're struggling to get people to show up right now without additional fees and with short wait times for everything and easier than ever boarding pass distribution. Are people really going to show up more with more covid restrictions, or if people are more concerned about their health, and added to that additional fees for some things? You might have the AP crowds coming, but they're unlikely to buy Genie+ and they're going to represent lower admission revenue.
I think the worse the covid situation gets, fewer people will show up, either because they're concerned, or because they don't want to go with masks or other restrictions. Effectively raising the price won't help.
