Marketing wise it would make sense.
“Welcome back to WDW, three new adventures to experience!”.
I know a lot of people have said its better marketing to wait for Remy till next year, but i don’t think so.
There is pent up frustration and demand. The only reason the parks are dead is peoples fear of Covid.
I know “dead" is relative. Opening it in 2020, would draw more people , and still be an attraction people will want to see next year.
More simply put, I don’t see people saying oh there’s only 2 new e-tickets at WDW I’m not going, but wait there opening Remy too, now im going.
But I do see people going to go see Remy when it opens, and people coming to see it when they open the others.
I mean they are dropping as many deals and discounts as they can to get people in the parks.
It would be stupid not to drop a new ride and get the draw.
All the park including USF, WDW, SeaWorld and Bush have started dropping rides every 2 years or so, I and I suspect if Cap Ex was infinite they would drop new rides every year.
Just my 2 cents.
