We were able to ride Radiator Springs Racers 5 times over the 4 days we were there, all with little to no wait. As I mentioned above, we took advantage of our two EMH days and walked onto the ride both mornings. On both EMH days, I got in the FP line shortly before the park opened to the general public. One day, I got FPs for later that morning. The second day, I stood off to the side of the FP machines after I got to the front of the line and waited for a FP return time later in the day that would allow us to ride the ride after dark (because I'd read so much about doing that). So we rode the ride twice on both of our EMH days. On another day when we had EMH for Disneyland, I hopped over to DCA mid-morning and got in the FP line, again waiting for a FP return time that would be after dark. Longest wait using the FP line was about 15 min. So we rode 3 times during the day and twice after dark. Loved getting to do both. I would certainly encourage others to ride Radiator Springs Racers both during the day and after dark for two very different experiences if you are able to.
