You would want all your guests to be comfortable. The same concept exists for self-help group meetings, you want your group members to be comfortable and at ease. Make sure there is sufficient, convenient parking and close to the entrance. Handicap washrooms are a necessity. No obstacles, such as steps, should obstruct your meeting site, and chairs and tables need to be set up in such a way to invite conversation.
Temperature is another important factor.
Your meeting room needs to be well ventilated and not too hot or too cold. Ask yourself if your meeting site is a place where you would like to spend a few hours. If it is an ordeal to attend a meeting and the atmosphere is inhospitable, you may find it necessary to locate a new meeting site. The best-planned meeting cannot overcome an inaccessible and uncomfortable location. Continuing the idea of guests coming to your home, we would consider it rude not to greet our guests at the door.
