Reddit mentions of Coleman Event Stool

YES!! Ask for the ADA sticker if you are experiencing "health issues" and are having difficulty standing and waiting for long hours and otherwise feel "compromised". They do not require "proof" of why someone is having health issues or what those health issues are.

• Also, you might want to modify your SDCC plans. Instead of going the entire day, you might be forced to go back to your room and rest, then return. That will be your judgement onsite.
  
  
• You should also be cautious about standing in outdoor lines in the direct sun. You should even be realistic about waiting in extremely long lines anywhere at SDCC if it appears that you won't feel well.
  
  
• You should BRING A SMALL CAMPING STOOL. There are many available on Amazon and you still have time to get one. This one was recommended by another subredditor as being a life-saver: https://www.amazon.com/gp/product/B00363WYWU/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1 It is also very light weight. I use the tripod style camping stools like this one: https://www.amazon.com/PORTAL-Slacker-Folding-Outdoor-Camping/dp/B073XDCQ4M/ref=sr_1_8?crid=2P1OZCIWTMYPS&keywords=tripod+camping+stool&qid=1562624571&s=sporting-goods&sprefix=tripod+camping+stools%2Csporting%2C206&sr=1-8 I'm very happy with it, but it is a bit bulkier, like carrying a poster tube. Do a search for tripod camping stools to see a large selection.
  
  
• It would be wise to carry some paperwork with you in case you fall ill and the paramedics want to know more. You can just keep something with you that explains your situation and how you've been feeling during your first trimester.
  
  
• There is a "mother's lounge" somewhere where people rest with their babies and children and there are private nursing areas. Maybe resting on-and-off will help. You will have to ask about this when you are at SDCC.
  
  
• There have been other people on this sub who have discussed attending SDCC while pregnant. I'm not sure how well the search will work, but you can try a sub search and see if you can read those posts.

That's a pretty good idea. I also carry a pocket chair which folds up pretty small for working on UPS's which are always on the bottom of our racks.

Quick thinking on your part then! Grab a little something like this and you can do the pose at the drop of a hat.

I just got the Coleman brand one here
