LA Auditions

So I posted this under another discussion but looking for some feedback on LA Unifieds. So anyone who has gone in the past I would love some info on how on time the auditions have been? Does each school hold auditions in a suite of rooms. or do they all have a larger conference room to work in? Do the kids audition on carpets or hard surfaces for mono/voice, sorry important for shoe issues for girls :). Are dance auditions held in a bigger conference room without bars and just a big space to practice steps? I know I am sounding so naive, but we are very new to this. Thank you.
