Traditionally, a Celebration Night or Wrap Party was a separate add-on night for guests to invite their friends and family to see what Alpha is all about and invite them to the next Alpha.
Many groups are now concluding with the "church" video and inviting guests one-to-one to the next Alpha when it's closer to the start date. The relational and personal invitation tends to be very effective. (See 5 Tips to Inviting Guests to Alpha)
Here are some ideas for the LAST Alpha session together:
Play one last icebreaker together (click here for ideas)
Watch the last "What about the church?" video
Have the senior pastor invite Alpha guests to Sunday service (5 min max)
Share a few ways for Alpha guests to stay involved (Home groups, Life groups)
Ask if the group would like to stay together and form a new Life group
Invite guests to share about their experience at Alpha. Allow plenty of time.
Provide Feedback Forms to your team and guests, digital or hardcopy (template can be found in the "materials" section, log in).
Share info about your next Alpha (start date, time) so guests can invite their friends and family to the next one
Ask if any guests would like to be a helper on the next Alpha
Take a group picture (this is fun online too!)
Arrange a group Zoom chat in 2 weeks to see how everyone is doing
