Well, there aren't park reservations anymore, so it's less "complicated" than it was 2 months ago.
So here's something to think about but this is all just me thinking out loud about Epic Universe and how it impacts Orlando as a whole as a destination ecosystem.
Let's list all the attractions at EU:
Celestial Park: Starfall Racers (coaster), Constellation Carousel (flat ride)
Super Nintendo World: Mario Kart (dark ride), Yoshi Adventure (dark ride) Mine Cart Madness (coaster)
Dark Universe: Frankenstein (dark ride), Werewolf (coaster)
Potter: Battle at the Ministry (dark ride)
HTTYD: Wing Gliders (coaster), Dragon Racers (spinner?), Dyre Drill (boat/dark ride)
Coasters: 4
Dark Rides: 5
Flat Rides: 2
That's 11 rides not including 2 stage shows.
Epic Universe is going to garner A LOT of hype. Brand new park, probably going to look awesome and have some great experiences. But it's 11 rides. That's Hollywood Studios. After 6? 12? months is there going to be a narrative that there isn't a lot to do at EU and it's a 1 day park? People consider DHS a half day park! (I'm not comparing ride quality, just quantity)
There is an argument to be made that EU might have the same impact (if not greater) on WDW as them adding a new ride. If there is some kind of data that people are going to less parks at WDW because of cost, i.e. skipping AK or DHS or Epcot during their stay (I believe
@lentesta asked the same question) then EU might give people an excuse to book a (shorter) WDW vacation to see EU when they weren't going to book an Orlando trip at all.
Just speculation but it depends on what happens on social media and what travel agents pick up on with guidance. Is EU worth at least 2 park days out of maybe 5 full days in Orlando (6N/7D stay)? Or is worth 1 along with 4 other days to do something. Is that 4 other days WDW?
I'm curious to see how the ecosystem reacts after the dust settles after opening.
