In light of the recent trend here on Micechat... I think the newest promotional at the park should be "The Year of a Million Themes"
Just think of the potential. We could have a theme that is theme discussion day. Then we could talk about the theme, and the sub theme, and the alternate theme and the hidden theme within the theme that isn't really a theme but it's about themes so I guess it should be in the theme discussion.
They could have a Disneyland Bathroom Theme day where everyone shows up with a roll of toilet paper. And the Walk in Walt's Footsteps to the Bathrooms of Disneyland tour. Instead of a riding crop the tour guide could hold up a toilet brush. We would ensure that the Bathroom Theme is complete by having all napkins replaced by toilet paper.
They could have a Disneyland ODV Appreciation Theme where they close all restaurants and everyone lines up to get food from the carts. This theme would be completed by Characters pushing carts around and selling you various ODV delights.
My favorite would be Churro Theme Day, where all ODV carts only sell Churros. The 50th Show would be converted into the "History of the Disneyland Churro" show. To maintain the theme the Tiki Room CM would wake up Jose by tapping on his perch with a stale churro. Splash Mountain would be renamed as Churro Drop, just for this day, and the Hitchiking Ghosts would be holding old moldy churros.
They could have a Magic Mountain Day, where they install temporary metal detectors in front of the Main Gate. Due to the severe importance placed on theme I have also decided that Buzz Lightyear's photo op should be moved to Adventureland, since being in space is an Adventure... actually he should roam between Adventureland and Frontierland. Per Startrek "Space... the final FRONTIER"... so we must maintian the theme. Merlin saw the future, so he does not belong in Fantasyland. He belongs in Tomorrowland, holding a large sign explaining how the world may end if we are not careful. Dumbo needs to be completely removed and tossed into Critter Country along with Mr Toad and most of the cast of Alice. They fit in Fantasyland, but unfortunately because they are talking animals... Critter has a stronger theme... so they need to go over there now.
Theme is the most important element of a theme park, and it must not only be maintained but celebrated. Please the suits at Disney, in celebrating the Year of a Million Themes... The best part is they can keep the sign and just use duct tape to cover up "Dreams" and change it to "Themes".
