Who should we invite? Just close friends? A lot of friends? Family?

The size of your guest list depends on you and whether you want to throw a huge celebration with everyone you know or just want to have an intimate gathering with the people who are closest to you. Huge anniversary parties are usually saved for silver and gold anniversaries (25 year and 50 year anniversaries). Your guest list also depends on the atmosphere you’re going for and whether you want a large bash or more of a backyard barbeque shindig. Often times, other people throw an anniversary party for the couple. In this case you’ll have to talk to the couple about what they prefer. If you’re planning a surprise anniversary party, you’ll have to be a little sneaky to figure out their preferences.
