  1. Hi there! My girlfriend and I just moved to Cambridge and are considering joining a gym in the area. We are especially interested in playing squash with each other (we are beginnners, but enjoy hitting it around together casually).

    Could you let me know how much membership would cost, both for a couple and a single person? If there are any additional fees for reserving a court, that would be great to know as well.

    Many thanks,

  2. Hello, I am looking for a jazz dance class that takes place at one of your facilities on Wednesday nights at 6:45 by Lillian Carter, could you perhaps tell me which facility this is at?
