Our pricing is monthly. Most months average 4 sessions, though some months have 5 of a particular weekday in them, and some months we're off for holidays so our hope is that it kind of washes out in the end.
If you need to miss a game for any reason, such as someone gets sick or the family goes on vacation, that's totally fine. We don't tend to refund for missed sessions unless we cancel a game (for example, if the Game Master can't make it and we couldn't staff the game), since even when you're not there we are still holding a seat at the table for you when you come back.
We do offer occasional special game sessions for make-up games, so if you miss your regular weekly game you can come in for a special one shot adventure on another day of the week. We will announce make up games when they are available and they will be posted on site as well.
