Where should I rehearse with other actors?

I'm currently studying part-time at two acting schools and obviously we have scripts that we need to prep, research, study and then rehearse with another actor or more. My question is (because our rehearsals are done outside of class time) where should I rehearse with my various scene partners? Right now I have about four different scene partners and I feel unsure if I'm just supposed to go to their house or where we should rehearse. I'm just a teenage girl and I would rather rehearse in more public places but it's not like you can yell, scream or cry manically in public (or do hardly any of your lines properly) without either getting stared at or in trouble in.

I trust my scene partners, but even for future circumstances where I might be unsure - what are some ideas for good (safe) places to rehearse with one or more actors?

And by the way, the studios where I take my classes is not an option. :) Also, please don't suggest my own home - I have a big family and wouldn't at all be able to rehearse properly with so many people around.

Thanks so much! :)
