So I'm limited to three? Hard. OK:
Peoplemover (if everything else is going then the PM can be rebuilt)
the only one really worth saving is Space Mountain, but if I must add 2 more, Star Tours and BLAB lol
space mountain, & i guess if you count the monorail & railroad stations then those too. the rest can go.
I was thinking more along the lines of longer transportation and more stops, but I wouldn't complain about a corkscrew either I suppose.
A would say a revamped peoplemover, Space mountain, and bring back caurosal of progress, they may not all be current rides, but those were the best.
The simplest approach would be to keep SM, ST, and BLAB and have the new Tomorrowland take on a space fantasy theme since those three rides have that in common.
Space Mountain, Star Tours, and Monorail. All the rest should make way for a new vision of Tomorrowland which doesn't involve Pixar characters. The monorail needs to be rerouted to make use of all that land, or figure a way to integrate it.
I think converting the land into an indoor track for a new Tron light-cycle attraction would be awesome. Utilize the existing peoplemover track to board and exit the attraction. Autopia and Innoventions would need to be sacrificed for the greater good. Depending on structural issues FNSV could be saved but I would personally change the theme back to its original concept if they are serious about making Tomorrowland the most entertaining land again.
BLAB or Astro Orbitor
Space Mountain, Star Tours, Monorail. Autopia likely not going anywhere. The rest can go and something fancy ambitious replace it.
But back on the subs and Buzz ..... I would never list them in My List ... because a romp with cartoons and attractions representing a plausible future for mankind ... or two completely different things. If the subs were on the list for a more "futuristic" layover ... then I'd like to see them stay. And for Buzz ... surely there are better ideas that aren't cartoons ... when Tomorrowland just isn't big enough to hold on to rides that don't really support it's theme.
Space Mountain: Yeah its just too iconic now. Its like POTC, HM, Splash, etc and has been built in every MK park. It would be weird NOT to have it at this point. It will be there as long as the land is.
Star Tours: I would say if they DIDNT update it, heave ho, but now its one Disneys best rides now. Its just incredible and it just opened in Tokyo to a lot of fanfare as well. And face it, Disney just bought Lucasfilm, no way is their ONLY Star Wars attraction will ever leave, especially with new films coming out. And now with 2.0 and going to multiple planets it means they can update it even more with the new films. They can add to it for a long time to come!
Monorail: God I cant believe I'm going to say this, but Walt built it lol. Im not a nostalgia guy in the least but is nice to have ONE thing in the land he designed and yes its nice to have some futuristic transportation (although its not really futuristic anymore since I been on monorails in multiple countries now). Anyway its a REAL functioning attraction and not just a 'ride' so that in itself is cool. And lastly, its just something about it after all these years to see it gliding in the air and hits all the spots in the resort. It would be nice to have a third stop in DCA or GCH but that seem unlikely these days. Anyway still great!
Buzz came really close as I love that ride too but since TSMM is there and really popular so its less of a blow if Buzz was gone (but would miss it). Everything else I would be fine they knocked it down.
