So just imagine that the Happiest Celebration on Earth was really a worldwide event, happening at not just the Walt Disney World Resort, but the Disneyland Resort Paris, the Tokyo Disney Resort and the Hong Kong Disneyland Resort...
I think if we are going to do this remotely realistically, we have to accept that WDWR will still be center of the celebration. It is Disney's biggest money maker and so why wouldn't you spend your money on advertising there? But what if the other parks got some new cool stuff also... Not including the Disneyland Resort, officially the Happiest Homecoming on Earth and the Happiest Celebration on Earth are two different things. The HHOE celebrates 50 years of Disneyland, the HCOE celebrates 50 years of Disney theme parks.
Well, correct me if I'm wrong, but haven't cool things already gone on at the other parks during the HCOE? Yes, many haven't exactly been acknowledged as HCOE-doings... but still. Anyway, here is what I can think of;
Tokyo Disney Resort
Well, I'm not really surprised with the TDR. I mean, they are not owned by Disney, the only things they rely on Disney for are licenses and Imagineers (I say that loosely, I mean I know Disney sometimes trains staff 'n' all but you know what I mean). Why should OLC give a monkeys for something happening across the ocean? Why would more Japanese people visit TDR because an American theme park is 50 years old?
A new plaque (well not even that) at 'Partners'
Disneyland Resort Paris
Now, this is where it gets fun. Space Mountain 2 and Wishes were officially part of the HCOE line-up, but the HCOE was not acknowledged in name in Paris - it was accepted that SM2 and Wishes opened to celebrate 50 years of Disney theme parks, occasionally mentioning Disneyland... But no HCOE merchandise etc. Again, why would French people give a monkeys?
Space Mountain: Mission Two
Walt Disney Studios Park
Toon Studios and TOT announced - but TOT was also announced at TDS.
Hong Kong Disneyland Resort
Okay, an entire resort opened because of Disneyland's 50th birthday (so they say) - what more do Disney need to do? Is it really appropriate for a full-scale celebration just ask the park opens for practically nothing to do with the park? People come to HKDL for HKDL, not Disneyland's 50th.
So, yes, WDWR basically is the HCOE. But I hope what I have listed opens your eyes slightly to why it isn't as easy as it sounds to implement the HCOE at other parks. At least most Americans visiting WDWR have heard of Disneyland at one point in their lives.
