This is good advice. I have a 3rd degree black belt in Tae Kwon Do. You're spot on finding a place that at least has adult-only classes. Adults and children train in completely different ways.

I'd also suggest finding a school that has emphasis on sparring and self-defense. Yes, the martial art is interesting, but at the end of the day it's practical to learn good street fighting techniques. Your martial art by itself isn't all that good for a fight involving guns, knives, baseball bats, and the like.

It's also good to have some ground-fighting techniques. You don't need to be a BJJ whiz, but you also don't want to be a fish out of water if you get taken to the ground. My TKD class was taught by a fireman, and it was 70% focused on TKD, about 20% on self-defense, and 10% on ground-fighting.

The school and the instructor are more important than the art itself.
