I also vote for CoP. One of the main problems is the first scene when Father mentions its right around the turn of the century.
Therefore, only 13 years ago we had another turn of the century. On the one hand, it would be great to update it to today, we have the problem of a ginormous gap in ending scenes.
CoP long ago passed it's ability to be a current attraction. I'm sure when they originally built it they had no idea that it would still be operating 50 years later, but in spite of the lack of love giving by Disney management it still retains a lot of it by Disney fans.
I just posted this on another unmentionable Disney base site, so I'll save myself some time and just repeat it here. This is in regards to the oft mentioned updating of the final scene.
'No you really wouldn't want them to update it because, #1 it isn't all that outdated as it stands. I still don't have an oven the recognizes my voice. Maybe some equipment like replace the video game with wii and a new flat screen, but other then that, it's fine. And #2 it really cannot be updated without losing a lot of the original. It is a terrific attraction because it is still entertaining and it is historical in more then one way. It tells today's generations what life was like at the beginning of the 20 century to what it was like toward the end of it. We live in the 21st century, we know what's here now no one needs to tell us and with advancing technology no one even tries to predict the future any more, it is all moving way to fast. #3 would be that it is just about the last major attraction that Walt Disney himself was heavily involved in during it's creation. Walt is dead, it seems like we should still be able to have a few things that started it all and contained a large portion of his imagination.
The funny thing about CoP is that the suits at Disney would love to have it break in two and let them haul it away. That explains why there has been so little upkeep done to it over the last 10 years. Yet, like the rabbit, it just keeps going and going and going. Hundreds of shows per week for almost 50 years now. Quick Calculation equals 260,000 shows. It makes me think that Walt shows up every night and takes care of the necessary stuff just to stick it to those fools that have control over his company now.'
Give it some love, clean up the auditoriums, paint and wash, upgrade the AA's, change the wording to early 1900 as @
EOD K9 mentioned, promote it as a "how do we know where we are going if we don't know where we've been" type of attractions, historic and created by WED, the man not the company.
