I think Univeral appeals to families, just families with older kids. But can I ask why they need to make Epic appeal more to families with young kids? My two cents, after my wife and I visited with our kiddo earlier this year, is that it was a park for the DINKs (dual income no kids). Outside of Yoshi and the carousel, there really isn't a single kid ride there. Which at first we were like, that's weird lol. But after time it started to make sense. Like they're trying to target people with more disposable income, which not many people have these days so to me it makes sense.
Also we kinda knew that going in. Basically the main reason we went alone was bc we knew he was still a bit too small for most of the rides and he probably wasn't gonna have the best time (plus he's still kinda learning to regulate his emotions so the whole thing would have been a chore). But that gave my wife and I more freedom to do stuff and buy stuff, frankly. Isn't that what Universal wants?
