In a telltale sign during my meeting with Six Flags (NYSE: SIX) President and CEO Mark Shapiro at Six Flags Great Adventure last week, I let the D-word slip. When he was describing an emphasis on future attractions that the whole family can enjoy together, I asked if that was the Disney (NYSE: DIS) mindset kicking in, and then I quickly tacked on a "no offense" in case it came out the wrong way. "No offense at all," Shapiro countered. "We should be so lucky."
