Waiting until children are older might work for some, especially if they are closer together. I first brought my children to Disney in 2010. My son was 10 months. But my daughter was already 7. My husband had died 8 months prior and regular vacations (small and large) are one of my "We can do this...we'll still be a family...this is not going to crush us" efforts. On a vacation the following year he'd become a runner and I used a harness. My daughter was never a runner, but they are totally different children in most ways.
I am far from a lazy parent. He was far from humiliated considering he has no clue what that means. If he did he wouldn't come running out of the bathroom naked. He was not yet at the point where he realized running off wasn't funny. He never did it to be difficult. He honestly thought it was fun. We vacationed here last summer and I forgot it a couple of days and had to chase him 3 times, but didn't lose him. He had my phone number on him. He's a recovering runner now at nearly 3.5. He realizes he shouldn't do it, but still has his moments.
We are here now without it because he mostly stays put and jumps around or plays a game while we are in line. We are here this week largely because when I mentioned summer vacation, my 3 year-old son talked about how beautiful it was there and how he could not wait to go back. He remembered last year's trip long enough to help convince me to do another. I love it here as does my daughter. He's the one that goes through the most changes on these trips, so it was significant for him to tell me he wanted to return, especially since this was the first year I had to pay for him. We are all having a blast.
I have seen quite a few harnesses this week. As far as I'm concerned, safety first however you have to do it.
It is obvious you are not a lazy parent. And as I already had said I am often wrong. In your position it makes perfect sense to use a harness being a single parent. That is a no brainer!! That is great that you can even find the time, enegy and money to pull it off. God Bless!
