Throwing a surprise party is generally a lot of fun and it makes the birthday person feel very special when they are surprised. That said however, surprise parties usually do not end up as surprising because someone along the line will mess up and spill the story to the birthday person and therefore, it is important that you know exactly who you can trust completely and who not to trust. If there is someone that you do not completely trust, you can simply tell them to keep the date free without telling them exactly what the occasion or event it.
Music and food
The most important aspects to any party are music and food. If you have a friend that does DJ gigs that can make a mixes recorded music, you can have him play at the surprise party either for a small fee or for free in exchange for the exposure and the advertising.
If your friend is trying to find out how to get DJ gigs at clubs you can even offer to help him in exchange for performing at your party. In terms of food, you do not have to do anything extremely fancy and most people simply love snacks. Have a friend make some small snacks or finger food for the party or you could even choose to order a platter or two from a restaurant or a baker. Keep in mind of course that most people will want to drink and dance and therefore, may not eat too much food because they will be busy dancing. As such, it might be a good idea to order very little perishable food and try to have a lot of packed snacks that you can open one pack at a time and keep unopened if the food does not finish as you expected. It is important for you to get lots of drinks however as most people expect to drink at parties while they dance the night away.You will need to find a way of keeping your bring in the dark and bringing her or him to the party. One possibility is to ask another friend to take your birthday friend out on an errand and to bring them to the location of the party on cue with an excuse of some sort. If not, you could always call you friend and ask him or her to meet you at the location for some reason. The key is to keep the secret from your friend whose birthday it is at all costs.
