hosting my first photowalk - things you hated/things you wished happened at the ones you've gone to?

i'd like some advice for hosting my first photo walk... it's a free event so i don't want to do too much leg work but i want people to enjoy themselves. did you enjoy the walks where everyone introduces themselves before starting or do you prefer when one person speaks and then everyone mingles on their own?

also - i'm having imposter syndrome for hosting this because I'm not a major professional, i'm just a photographer with a small portrait business seeking more local community and collaborations.

any general advice is welcome
