The cost of your family occasion will depend on how big you plan to have the party or gathering.

1. A large party with many guests will prove to be costly because you will need more food and drinks.

2. If you choose o hire a party planner you will save yourself the trouble of having to arrange everything but they also come at an additional cost.

3. Most family gatherings range from as little as $50 right the way through to an expensive banquet costing $3000 or more. It will all depend on how much you have available and what type of thing you want to do for your event.

4. Home cooked meals provide an intimate alternative to the often garish nightlife that can quickly become expensive if you have many mouths to feed.
