Mine are in their hide for most of the day but when I go to get them out and handle them, its usually with no complaints from the snakes. They like to be held and they seem reluctant to be put back in their enclosure. So as far as the nocturnal thing goes...I dont see an issue with taking them out during the day. Usually when they dont want to be bothered, they can deifinitely let you know!
I agree with everything you just said. And for the last comment, I got my first hiss the other day! It was a big moment for me. haha
