What kind of light diffuser or modifier do you guys all recommend for a convention centre environment where the walls and ceilings are too far to bounce off of?
I shoot in these conditions on a regular basis. A diffuser does not help you if there are no bounce surfaces. All a diffuser does is send the light in every direction. If you are surrounded by nice bounce surfaces then diffusion can be helpful, if not, you are just throwing away flash power.
If there is no way to bounce I shoot the flash direct and drag my shutter. This picks up some of the ambient light to keep from having a bright subject on a black background. If there is a pronounced color to the ambient light you can gel your flash to match it.
Going to off camera light works, too. I shoot in one venue that has a 75 foot high ceiling. I put a light in the balcony and aim it at the ceiling. I put another light on the other side of the balcony, also pointed at the ceiling. These lights are on separate Pocket Wizard channels so I can pick which one I want to use. The light is coming from different directions so I pick the one that will give me the light I want.
I shoot in another venue where every surface is either dark stained wood or old bricks. I shoot with an off camera flash aimed at one spot. I use it when my subject is facing it, and I use on camera light when the subject is facing another way. I also use the off camera light as a rim light when my subject is facing me with his back to the off camera light.
