One of the places I'm looking at gave the option to watch and do a trial run at another time with a female friend. Or to try it out straight away, only caveat being that I'll probably be paired up with a guy.
I have a friend who might be able to go with me at some point. But that could be a few weeks.
What do you think works better?
You could do either, but personally, I like to watch at least 1 or 2 classes first. This way, you can get an idea for what the classes are like. But as I said, you could also jump right in, if the teacher allows that.
