The meeting room that you select will depend on several factors. Most obviously, where does the meeting need to take place geographically, and what type of facility will best suit the meeting? Hotels are a very common choice for meeting facilities, but there is also a multitude of other options available. Investigate meeting at a college, country home, museum, or in a high-rise.
Do you need to have high-speed internet access? Even if you can't immediately think of a way that you would use the internet during this meeting, it often comes in handy when you least expect it.
What kind of audiovisual equipment do you need to have available? Also, what kind of business center services or trained support staff might this meeting necessitate?
What kind of activities will take place during the meeting, and what type of set-up will they require in the meeting room? Many meeting facilities have flexible furnishings which can accommodate several different types of activities (presentation, panel discussion, large group discussion, breaking up into small groups).
Finally, do you need food? If the meeting is an all-day training session, you certainly do need food. Even if it is a much shorter meeting, food makes people happy -- it makes them glad they're there. Coffee is also a necessity in today's fast-paced, high-powered business climate!
