Then... imagine the amount of money that Disney (might be)/(is) holding out for. ;-)
I suspect that Disney also has Disneyland Paris influencing its decision whether or not to go in Dubai. Dubai's primary market seems to be Europeans, and Disney's got its Paris franchise to protect in that market. (Which is why I found the Legoland announcement a bit curious. Perhaps Merlin's taking a counter-intuitive approach and hoping that its presence in the heavily-hyped Dubailand project drives interest back to the closer-to-home European Legoland parks?)
The name "Cedar Fair" has no brand value. Cedar Point has limited brand value outside the Midwest and the Peanuts franchise has lost much of its brand value over the past decade. So I can't see CF as a player in Dubai. I think that Six Flags has that market niche covered.
Maybe this whole Dubai thing is just some very secret US Government plot to further Westernize the Middle East?
You heard it here first....
