First order of business for Tilman Fertitta, now that he’s finally succeeded in turning Landry’s Restaurants back into a private company under his control (the deal closes today): announcing the demolition of Galveston’s hobbled-on-a-pier Flagship Hotel. Actually, Landry’s officials jumped the gun slightly, showing plans for a large hotel-free amusement park on the 25th St. Pier site of the shuttered hotel to Galveston’s city council yesterday. In place of the Flagship — which was built a few years after Hurricane Carla hit the island in the early sixties — yep, you guessed it: There’s gonna be a Ferris wheel. Plus: a double-decker carousel and other attractions meant to vaguely resemble the amusement park originally on the pier when it was built in 1943.
