The restaurant/bar at the top eliminates the little guys, as well. Fun Spot has a hot dog counter, I don't see them trying to get into a real restaurant. Too extreme/expensive for Old Town, and bar eliminated Legoland. Doesn't "feel" Disney. Sea World makes more sense to me than BG for some reason--I'm thinking out by the old stables--but I don't get the sense that either park is looking to drop a lot of coin. Plus this doesn't seem terribly family-friendly. And I'm ruling out Universal because HateToFly seems stymied--seriously doubt this would be signed without he (or WhyLightBulb or the Spirit ...) hearing rumblings.
Miami would offer the best views, but where do you put it? By the arena? The only touristy area anymore is South Beach, and this just seems the opposite of everything in South Beach. Miami prides itself on not being Orlando, and this coaster just screams "Orlando." Daytona is a long-shot, but this is a huge step up financially from a run-down water park or a skycoaster.
My guess: I-Drive, not as a part of I-Drive Live, but a parcel within walking distance and sight of it. An attempt to siphon off some of the expected crowds, a higher-end version of the Fun Spot/Old Town situation in Kissimmee.
