An open house party is a party that is held at a home or other location for a set number of hours, and during those hours, guests can come and go as they please. Open house parties are more informal than other types of parties, and are typically easier to plan. Open house parties are also beneficial if you want to invite a lot of people to your party, but don't have the space to accommodate all of them at once.

An open house party is often held in lieu of a traditional housewarming party, but you can have an open house for any occasion or holiday you choose. It is not necessary to plan activities the way you often need to at other types of parties. When you are planning an open house party, there are some extra considerations to keep in mind.

The first issue to consider is the invitations. Include all of the usual information, including the occasion for the party and the location. Instead of a specific time to be there, however, the invitation will state a certain number of hours during which guests can stop by. Some open house parties last all day, from morning until evening, but others only last a few hours in the afternoon or evening. It is rather counter-intuitive to ask guests to RSVP to an open house party, but if you want a general guest count, you can include that information as well.

Another issue to keep in mind is the food. You will want to make enough food that can last the length of your party, but won't lose its appeal after sitting out on the counter for hours. Simple snack foods are best, unless you want to cook food a few times during the day. Another option is to make the party a potluck, and ask each guest to bring a dish. Make sure you have a lot of different beverages available, and let guests know if alcohol will be available, or if they should or should not bring their own. Some people do not want children at their open houses; if this is the case, be sure to indicate that on the invitation.

An open house party can be a fun, casual way to spend a day with your friends and family, showing off your new home, or celebrating a special event. Summer picnics also work very well as open house parties, because people can sit outside as well. Remember, once the party is planned, just relax and have fun.
