What time should I write on the invitations if I want ensure the activities start on time?

On the invitations make sure to write the start and end time so your guests’ parents will know what time to pick up their child. It’s also a good idea to add directions with your invitations so guests can know ahead of time if it’s going to take them a while to get there or not. If you have something planned at a specific time such as lunch or a movie time make sure to write it in the invitation, such as “lunch will be served promptly at 1:00 pm”. Make sure to set the start time at least 30 minutes before any important activity is supposed to begin.
