I use a Panasonic ZS100, which is very similar. For many, many years, this camera could go in without problems. They'd look at it, say "point n shoot" and in it would go. Your Canon should fall in the same category.
That said, this summer, I've seen rules that say, "point n shoot with a zoom less then 1inch." At some venues, they make me power up the camera, and since the zoom sticks out longer than 1 in, I can't bring it in. Other venues, they aren't so picky. It all seems ridiculous as everyone walks into the show with an iPhone that can shoot very well.
Can anyone else that uses a point n shoot post about their recent experience?
