This is a debate that came up in the "Absolute Weight of Theme" thread and I thought it would be an interesting topic for a poll.
Personally, I am currently wavering between Options #1 and #4.
When the park opened, it was definitely Option 1 - on the Opening Day TV special (1955) Bob Cummings clearly states that the land was set in 1986.
I'm fairly certain Tomorrowland '98 was supposed to be Option #3, taking a cue from Disneyland Paris' Discoveryland.
However, this poll is about the current Tommorowland...and I'm not sure
I'm only sure that it's not Option #2 - which is exactly what someone in the other thread was arguing in favor of.
The plaques on the entrance tunnels state:
"HERE YOU LEAVE TODAY AND ENTER THE WORLD OF YESTERDAY, TOMORROW AND FANTASY"
(capitalized because that's how it appears on the plaque - I'm not shouting
Even if there is debate over what is meant by Tomorrow (as there was in the other thread), "HERE YOU LEAVE TODAY" seems clear to me. If the idea is that in entering Disneyland you leave today, then neither Tomorrowland nor any other land can be set in the present, or at least not the ordinary present that we live in.
