In the past, we have been asked to leave the load/unload area and wait outside the exit for the rest of our party to ride after he chickened out. I believe they do not allow anyone to wait at/near the loading platform due to safety reasons.
When he gets cold feet, he will express it by pulling on me (he's nonverbal) and attempting to leave. If that were to happen, my partner could probably ride while I comfort my son...FAR away from the queue. I was just hoping there could be some way for me to ride afterwards since we technically have already waited the entire duration of the stand by wait time. If not, it's not a huge deal for me. I'm used to missing lots of things over the years due to autism. lol
