Here's my speculation.
So I believe that in general, Epic Universe can not afford not to start constructing for expansion as of right now. Due to a drastically lacking attraction lineup than people's demand. It was way more overwhelming than what they simulated and the park is not even at full capacity. But the general wait time in Epic is already one of the highest in the world. Mario Kart, Donkey Kong, Battle at the Ministry, Wing Glider, Stardust, and almost every attraction without unchained is listed at least 1 hour in general. and the highest often caps at 4 hour wait, which I find not normal. Also, rides consistently break down due to new technological difficulties, and 60% of attractions is located in outdoors, which makes it brutal for Florida weather; rides down very often due to weather conditions.
We love Epic, but let's be honest, general audience reviews have been pretty rough. Yelp, Google, and TripAdvisor are full of complaints, and the park’s information booths are constantly crowded with guests asking for refunds it’s happening everywhere. They say that the park is beautiful and amazing but often heavily criticized for park management on crowds and extreme wait times.
Imagine a general audience paying like 200 bucks individual or often 800 bucks for the whole family for one day at Epic, which is a pretty expensive investment. and able to get to only ride 3 or 4 attractions due to heavy crowds and downtimes. That's far from reasonable at all for paying 200 bucks.
Getting bad reviews for a year and showing noticeable improvement after listening to feedback would make sense(like Volcano Bay), it would show that they care about guest experience and long-term quality. But instead, they’re planning to raise capacity even further by the end of the year, which will only intensify the existing problems. If this trend continues through 2029, four years after opening, without any major expansions or operational fixes the ongoing wave of negative reviews could have a serious impact, not just on public perception, but also on future earnings calls, investor confidence, and the company’s overall reputation.
That's why I think that new attraction expansion will be completed around the end of 2028 at least, and between the construction of this experience, construction for other expansions will begin as well.
I believe that they can't simply afford to do nothing by the end of 2029.
