OK, so, yes, there's nostalgia.
But it was the biggest, best example of the sort of ride that only Disney does.
Mission Space is a thrill ride that is in some ways similar to other motion simulators--but more intense.
Here is my thought that would bring M:S up to Horizons standards.
Indulge me as I dream a dream.....
-You go into the capsule, and take the ride as you currently do.
-When you get out of the capsule, you walk out a door and onto another "bubble" vehicle...BECAUSE YOU'RE ON MARS!
-Then, "Horizons" (or, say Haunted Mansion) style, you're taken on a tour of the Mars base, culminating in a huge IMAX dome with the terraforming martian landscape and atmosphere all around. (Cue Ozone fresh air smell)
-At the end, you're put into hypersleep and taken back to earth in a "new transport" of some kind--no need to get back into the capsule and endure the spinny part again. Back to Epcot.
Ahhh, now THAT would be a worthy successor to Horizons.
I always find it odd that the ride takes me to Mars, and Mars ends up being a long hallway to a gift shop. With vomit canisters along the way. :lol:
