Yeah... I see that, LOL! Sorry, didn't mean to open that can of worms. I legitimately was trying to figure out the best way to handle my condition.
It sounds like people would be less annoyed if I get in line first and then duck out if I need to use the restroom again. Sometimes I go, and then five minutes later need to go again

So rather than just sending my family ahead, I should go with them, and then pop out if I need to go again. And only while the line is outside and there's no squeezing past.
If I'm having a bad flare, I'll consider the
DAS but under normal conditions, I don't think I'll need it. My symptoms come and go (i.e. "flare"). I might just need an extra trip to the restroom here and there.
I personally also think that it really depends if the addition of a person is going to change the wait time for the people behind. In my case, it wouldn't because 3 people vs 4 people wouldn't use up another car or row - the seat would most likely just be left empty if I wasn't there.
