If you're involved in planning larger-scale games days (roughly 25 people or more), or if you'd like to organize such an event, consider joining the Games Day Planning discussion group.

The GDP discussion group includes members from a variety of locations who are experienced at organizing gaming events with a couple of dozen participants up to a couple of hundred participants.

Some of the events they've scheduled are single-day; others are multi-day gatherings that include special room rates at hotels.

The best part is that they're all willing to share their tips and experience to help make your event a success.
