I use the chicken exit often, even on rides that I DO like to ride. Some of them are rides I wouldn't take my camera gear on because I wouldn't want it stored in a bin, banged around, or risking getting wet, so when I ride those rides, I tend not to bring the full camera kit. But when I do have my good camera gear, I want to photograph some of the queues, so I'll go through the line taking photos, letting people pass me, then bail out before the ride boarding - I just tell the CMs I went through the line to take photos. Never been a problem on any ride at Disney.
I've done the queues for a few of the rides that I don't ride - like Mission Space and Rock-n-Roller Coaster ( I can't do circles or loops - it's the one kind of motion sickness I'm susceptible to. Don't mind big drops or fast turns, but if it goes around in circles, spins, or does loops, I'm out). Even the carousels and teacups are no-nos for me.
