Great post. There's a lot of opponents other than just Disney to gambling in Orlando. I'm sure the bigger resorts--Harris Rosen's empire and Gaylord Palms come to mind--don't want the competition either. Nor do I think hard R gaming fits the PG-13 image Uni is going for.
That said, I think there is still too much old money and high-0end resorts around Tampa to ever see casinos there (plus what do the Scientologists think of gambling? They pretty much run Clearwater, no?). Only places in central Florida I could see it are up in the Villages somewhere--surrounding Bible Belters will probably fight it tho--or Daytona Beach, which already resembles Atlantic City in a lot of ways and where the France family can force it through if they think it will bring in a few more bucks during Speed Week. In any case, i agree, an hour away at best, and more likely confined to SoFla.
