Toyland Tours without a doubt.
So many memories tied to that ride, and I was genuinely sad to see it go. I was (perhaps foolishly) hopeful that Charlie would be just as captivating and full of imagination as Toyland was. The reality however was far from great, which IMO makes Toyland's demise so tragic.
The ride when it was new was full of life, never had a dull corner to look at, was upbeat in its musical score and had a bunch of really memorable set pieces (the Sonic scene, the chubby checker, the 'dolly' mixtures amongst others). Even when some effects weren't working fully, it still had a ton of character. Its popularity sadly waned towards the end of its life, and its last day was just as eventful as the days leading up to its closure, and before we knew it it was completely gone without a trace.
Then Charlie turned up... and the response it got was less than favourable. So sad that a ride as good as Toyland lived, subsequently died with nobody caring, then was replaced by something so inferior, which made us realise the treasure that we had lost...
...Well that got poetic and pretentious as hell
But yeah, I miss that ride.
