Unless you are a self-confessed hostess, attending a party is easier than hosting it. The former includes more preparation, whereas as a guest all you need to do is eat, maybe talk to a couple of guests, and enjoy. As a host, you need to ensure that everything is perfect, and the only way to do that is by eradicating the problems.
The Food or Supplies Run Out
In order to have a successful party, you need good food, great company, and the best ambiance possible. Let us go to the first topic, which is food. As it is essential to keep the party goers interested and happy, you should always have extra stock handy. If you are not having an RSVP event, expect to have more guest than you have anticipated. This is especially true for an open house party wherein your guests can bring their relatives and friends. Stock more food and have a runner ready in case the supplies threaten to diminish.
That Awkward Moment
Awkwardness happens when one guests does not know another. Not everyone is comfortable enough to go to another person and introduce themselves out of the blue. As a gracious host, it is your duty to give introductions first before leaving everyone to their own devices. Tell them how and when you met, and give them a chance to continue the conversation. This is ideal if not everyone belongs to the same group.
Uh-oh, They Are Getting Bored
Music can only take the party so far as you want. There needs to be other forms of entertainment as well. Try to think of a game which everyone can participate in. For new friends, an ideal one would be ice breaker questions, followed by a dare if they cannot say anything about themselves.
Hosting involves a lot of planning, budgeting, and sometimes all the help you can get. There will be problems lurking here and there. You need to anticipate what they are so if ever it presents itself, you are armed, ready, and know what to do to get on top of the situation.
