1. I think most of us only have a problem with people on rides or attractions using phones. 5 minutes won't make a difference.
I agree. I've been to WDW when my parents were having constant health problems (it finally got to the point where they had less than 2 weeks between ER visits) so I had my cell phone turned on all the time, but on vibrate. Even if I had gotten a call saying one of them had died, or was in the ER, there really wasn't anything I could do about it until I got off the ride, and I was still 3 hours away. So 5 minutes wasn't going to make a lot of difference one way or the other.
