Decide where you want to go first. Think about if you want your fun to involve going out dancing, drinking at a bar, listening to live music, watching a movie or playing miniature golf. Once you have decided, set the theme. For example, create a "Hollywood" theme for a movie night.

Think about how many people you want to have. If your activity doesn't have space constrictions, tell your friends to bring a friend. The more the merrier.

For a fun twist, ask your friends to dress up to match the party theme. They can dress as dancing queens for a dance night or movie stars for a movie night.

Send out invitations or email invitations to all of your friends. Match your invitations to your theme for added fun. If you chose a "Hollywood" theme send invitations in the shape of an Oscar award. Send invitations in the shape of a martini glass for a night at the bar.

Decorate your house to match the theme. Hang old movie posters for the "Hollywood" movie night theme. Set out buckets of popcorn and movie candy that can serve as decorations as well as snacks.

Have your friends meet at your place for drinks and dinner before going out. You can supply the main dish and have each guest bring a side dish. Let everyone know what type of food to bring such as Mexican, Italian or Chinese food so all the dishes go well together.

Invite your friends to sleep at your place, so they won't have to drive home late.
