Wait, TSI is being removed for Cars Land in Tokyo?
No, thank goodness. That was circa 2012 when OLC was shocked with their massive 20%+ increase in attendance and profits the 30th was bringing in. Management thought their park business was mature until that point and were fairly content that it had plateau'd. They really didn't actually 'do' a whole lot for the 30th. To expect 6-7 million more guests to suddenly turn up from what Tokyo Disney and Disney Sea combined had been averaging caught them way off guard. The Tokyo 30th was lovely, but I thought the DL 60th was much more impressive.
The last major addition was 2008 with their Tower of Terror, you can really appreciate how attendance explodes out of nowhere this decade. Even coming off the biggest disaster any Disney Park worldwide has even seen in 2011.
Then they went to WDI, flush with cash, desperate for capacity. They came back with essentially: "Well Carsland was really successful, you can have that. Or you can help WDW pay for Avatar, we'd really like you to do that please". It was one of the strange reasons Pandora didn't show up at D23 2013 in Anaheim and yet was present in a very big way in Tokyo later that same year.
They turned that all down, asked for something unique and came forward with the rather (in my opinion) great idea of the Fantasyland expansion with a moved and completely redone Small World, B&TB E-ticket, and Alice miniland with its own E-ticket. It was all to be topped off with a new Arrendale expansion in Tokyo Disney Sea before the end of the decade.
It was all ready to go and money was already allotted for it last fiscal year. Then it was delayed, for reasons many have commented on, but no one has completely nailed down. SDL, the Olympics, WDI, lots has been speculated about, some of it is probably inaccurate.
But Carsland is definitely a dead proposal.
