I believe one must be on the committee to have access to the minutes of the meetings. While many of the committee meetings are open to the public, there are executive sessions that are not open to the public.
AWS does not coordinate or pay for many of the meetings held at the subcommittee level. The committees usually try to meet somewhere that allows to us to use their facilities without cost. However, travel, lodging, and meals are paid for the individual committee members. AWS does not charge the main committee for meeting rooms held at headquarters, they usually have coffee brewing and they send out for sandwiches for lunch.
