Nothing at all. Open it back up, make TL more inviting to guests. I always thought placing that beast in the entrance was too constricting to crowds, and now with the Buzz que, it chokes off that side pretty badly...
Honor those who fall under the sword.
But pity the warrior who has slain all his enemies.
I am all for a smaller fountian or something to pay tribute to TL of the past. I would love to see all the plans Al talked about happen. Really doing the peoplemover revamp would be more costly then anything else having to redo the full track. Also would they keep the stairs and elevator in the center or bring back a speed-ramp?
Then there is a BIG problem that will have to be looked at again.....how to get people from the ground up to the Rockets again. I think the elevators were the biggest problems with the attraction the first time. It would take forever and it always seemed that one of them would be down for some reason. Again I would LOVE LOVE LOVE for both of these things to come back to us and hope they do. I just really can't wait to see how WDI takes on these problems in the 21st century.
Leave it open, and concentrate on revamping the rest of TL.
Bring back Tomorrowland Terrace, with good family bands.
Something new and spectacular in Innoventions,
Something new in HISTO,
and (can't we dream) A Star Tours Up date!
