Most of those complaints have more to do with the ecv, and the invisible nature of such. I have done disney in an ecv alone before. Three days at DL. There were rides I couldn't ride because I couldn't transfer alone, etc. I ordered food or drink based on what I could deal with on my own. I could complain about not having the same experience or enjoy the fact that when all the benches were full I could park my cart under a tree and enjoy a mickey bar.
I have never had a 20 minute wait at a qs restaurant at Disney. 5, yes. But that is due to good planning on my part. That 5 minutes in our lives consists of finding enough chairs to huddle around a single table, Getting the little ones settled, making room for my mom and her ecv, etc. That time would be taken to do those things regardless of when we start. The table will be occupied for the 20 minutes. It isn't shortened if we waited the extra 5. The time just comes off the other side. That is what you don't realize, not having experienced it.
Per single parents with kids, I have run around as a single with 9 kids including one with severe disabilities. You just take the circumstances, and deal with them. You plan well, and roll with what life throws your way. Would that parent benefit from having their kiddos set up when the food comes. Yes. Do you always have someone to do so? No. So, you make a picnic, find a chair without a table, keep the kiddos in the stroller. See the line, whip out the snackie bag, and wait an hour. Whatever. It is not difference than dealing with the same issues outside of Disney. Most moms or primary care dads know the ropes and how to deal with them.
I know that you will not agree with my post. Seeing two sides of an issue is difficult.
ps. In my world if you have a bathroom emergency you are welcome to rejoin the line. But that is how I see the world.
It is about being kind and having compassion. And, my family will be the first to grab a door, offer a chair or to carry something for you, or to step back and clear space in a crowd. They understand a brother in a wheelchair with cp, a grandma in a wheelchair due to complications from chemo, and a mom who is occasionally confined due to my issues.
My vacation happiness has nothing to do with getting a table or a place in line. We have had too much real tragedy to do anything but smile, be grateful, and appreciate the opportunity to be with one another.
