Multiple Coaster Contract "deals"

When it comes to the amusement industry, I believe anything is possible. Multiple coaster contracts? Why not? The same people who 20, 30 years ago who said there would never be a 400 foot coaster are probably the same ones who claim it no park has ever or will ever have a multiple coaster contract. Not that I'm saying these things do exist, it's just that anything is possible.

No one has ever presented any direct information of vague  multiyear coaster deals.  I'll believe it when I see the contracts.

Yes parks do go back to the same manufacturer more than once.  Just like the rest of us, if they get a good product, they are likely to go back for more.  Also, if a manufacturer has had a good ecperience with a park, he may lower his price somewhat since he can feel that he is less likely to have problems.
