I like to have a few classes offered. Our retreat usually has one of the members to teach. Ours typically has 60 to 75 people. Ours has food supplied. Sometimes we have a couple of vendors. We usually have a few door prizes. Some are donated by members and some from the LQS. We also have a snack table set up. People bring snacks to share and we just have a big table full of yummy food. We also have a table with things we no longer want. Free to whomever wants it.
In years past we have had a silent auction of donated items. The money raised goes to next years retreat deposit. It is so much fun and such a relaxing weekend.
