Planning a special event is of course the most important aspect, and the choice is easy: plan and organizes it yourself, pay someone else to do everything for you, or halfway. The obvious advice is that the more you do it yourself, the more money you'll save. If you are a resourceful and organized person and you have the time and energy to do it yourself.
However, start planning early. Don't wait until the last minute. You will regret it. If you want to leave it to someone else, there are capable planners everywhere who will be happy to work with you. If you rent one, give him ample time to do the job carefully and in detail. This will help you to plan special occasion on a small budget.
It could be your house or apartment, or it could be the Staples Center. The key is to be comfortable for you and your guests. Things to keep in mind are: how big is your budget, how many people do you expect, how many kids will be running around and tripping over things.
FOR EAT AND DRINK
If it's a short event of two hours or less, you can get drinks and snacks. Anything longer requires a complete diet. This can be a buffet or a sit-down meal served by a waiter. It can be served as a buffet with dishes served or a kind of self-service.
Music delivery can be a simple setup, but the music should ALWAYS be there. Music will remind your guests to have fun every minute of the event.
