I’ll take a cynical guess at the new marketing/GMA/higher cap push…
The parks in general have subscribed to a push for fewer guests, more new guests, more spend per guest. Figure a large percentage of rD racers are returnees - a fair number of those are like me: BT/DT, aren't buying a ton of merch (I haven’t bought ANY in years), aren’t registering for every race anymore, aren’t spending a bunch in the parks, aren’t doing long stays with more nights on property. That’s not their target audience anymore. Maybe the new rD push is to better align with the parks goal: get more new, high-spend runners into the field, those who are likely to drop a lot more cheddar while visiting. Entice them with Insta-worthy marketing that makes every minute of racing look like it could turn into a viral post. rD/WDW doesn’t need to care about whether races are congested or lacking support or leave runners feeling like they didn’t get their money’s worth if the goal is make quick bank off folks who are one-and-done.
