If we were going by the "a couple of people don't mind so it must be ok" scale I would also say that a few people also don't mind being hit by backpacks, having smokers block the exit doors, walking around people using the ashcans as tables in the intersections, having people be rude to them or make a snide comment, being held up by photography sessions in the aisles, or people being late or disruptive during games. All of this is still bad etiquette and there is no excuse for doing it.

But you hit the nail right on the head- they are a huge inconvenience, and they are a huge inconvenience in a very high traffic area full of people who aren't always aware of their surroundings. Nobody can just expect people to be alright with that.

1) Training Grounds is not a designated stroller area.  There is nothing in the description of it, and nothing posted by GenCon that even suggests it is a "designated stroller area".

2) The Family Fun pavilion is a portion of the exhibit hall that is oriented towards families.  If you have ever actually gone into it, a substantial number of the booths include toddler and infant games / toys / products.  The family fun pavilion is also distinct from the training grounds (It's all the way across the hall from it).

I don't know where anyone got the idea that strollers have a designated area they are allowed in, but that is not the case.  And, for a convention that is pretty expressly expanding in the direction of families, it would be pretty stupid for them to limit those very same families from the marquee attraction.

Not that you are allowed to bring strollers into the rest of the exhibit hall just as you are allowed to be rude to people, not pay attention to where your backpack is when you are around other people, stop in the middle of the aisle for pictures, hold up games by showing up late, block the exits while you smoke, stop in the aisle to take pictures, not take a bath or change your clothes, be a sore loser when you lose, and use trash cans at intersections as tables. That does not make it ok.

Sorry, but if you are planning a vacation with very small kids who need a stroller part of being a good parent is realizing that you are restricted in what you really should be doing. Outside of the areas set aside for little kids the exhibit hall aisle are not a place for strollers. rather than saying "too bad, suck it up" to everyone else in the hall you should be looking into child care, taking turns in the hall with your spouse/family/friends/whoever you came with, visit a few booths while someone else watched the kids in the family areas, or just do what parents have done for generations- realize that little kids are not going to be able to do everything that you want to do on vacation and change YOUR plans accordingly. There is always next year, price of being a parent.

GenCon is actively trying to be more attractive to families, and families with young kids are part of that effort.  It is not poor etiquette, or rude, for families with strollers to be in the dealer hall any more than it would be for someone in a wheelchair, or on crutches, or with a walker, to be in the dealer hall. 

Good etiquette is also placing the wellbeing of others before your own. 

Also, as I have pointed out, there is a LOT to Gen Con that is not the exhibit hall, there are sections of the hall that are specially set aside for little kids, there is a spa program full of activities for kids, and there are plenty of games outside of the exhibit hall that you love to see a youngster in a stroller. 

Make no mistake, you are CHOOSING to disrupt traffic and put your children in a questionable setting when you try to bring a stroller down the aisles of the exhibit hall.

Gen Con is not just about the dealer hall. That is a small part of the overall show. besides the rest of the convention center there is an entire stadium and several hotels worth of things to do that are more appropriate for kids in strollers.

You again hit the nail right on the head- placing the wellbeing of others before your own is the hallmark of good manners. Bringing a stroller into the exhibit hall aisles is creating a potential hazard for your child and an obstruction to everyone else, you are sacrificing their wellbeing for your own. By definition that is bad etiquette.

And yes there are horrible parents in the world, but it's not our responsibility to tell them how to raise their kids. No one has a right or a responsibility to tell someone what to do with their child. If you see a situation wherein a child is in that much in danger, alert the authorities.

Finally by your agreement that good etiquette is sacrificing something for the wellbeing of others, I just don't get why you are so against strollers. Shouldn't you, as a practitioner of good etiquette, whenever you see a stroller and recognizing that the young parent has a lot more challenges in the hall then you do, step aside, smile and wish them a good convention?

Sure, you can just not care about it, but then that goes for literally everything people are mentioning in this thread. It's the etiquette thread, not the vigilante justice thread. You're free to do what you want, people are just mentioning what you shouldn't do because it inconveniences others. gharris isn't doing anything to the stroller people.

EDIT - Here's a link to the dealer hall map for this year.  Note the area labeled "Family Fun Pavilion"

There are also instructions for parents on how to conduct their children: "you should be looking into child care, taking turns in the hall with your spouse/family/friends/whoever you came with, visit a few booths while someone else watched the kids in the family areas, or just do what parents have done for generations- realize that little kids are not going to be able to do everything that you want to do on vacation and change YOUR plans accordingly. There is always next year, price of being a parent."

Honestly, I get that strollers are an inconvenience in the exhibition hall, but come on. As a father of two little boys, you definitely want a stroller over the other stuff. Now, I don't bring my kids to Gencon yet, but they've been to plenty of other large events with big crowds.

How else do you expect me to carry around everything I need for them? Little kids need snacks, diapers, wipes, changing pads, water/formula/milk/juice. How about the books or small toys that tend to travel with little kids? There's usually a blanket or two if it's going to extend around or near nap time, or the lighting is crazy bright for the baby. Let's not forget that you also need extra clothes because who knows when the 5 month old will explode or the two year old will decide that his PB&J works better as a paint set for his shirt than as lunch.

You might as well tell parents they're banned from the hall. Granted, I'm not going to bring a double jogger, but strollers are wonderful and almost necessary for long days out.

Just put up with it so that young parents who bring their kids can enjoy the con.

For a community that tends to be extremely supportive, I'm shocked by the lack of support for families with young children that I've seen here.
