Earlier I suggested that you have a good bag to protect your camera. That's fine for when you're not using it. But at at show like San Diego Comic Con or Star Wars Celebration, your camera is going to be out and being used all day and night.

The best way to keep it safe...the strap. Whether it is a wrist strap or neck strap, just use it.

It's their for a reason. You may think you have a good grip on the camera, but it only takes a small bump to send it flying. I've seen it happen too many times and the camera almost never survives.

If you don't like the strap that came with your camera, that's ok. There are plenty of after-market straps you can purchase that may be much more comfortable.
