8. Time Available

The amount of time you have allotted for your party will dictate the amount of games or other entertainment.  Have a schedule but don't be a Time Nazi; if the guests are enjoying a certain game let them keep playing it even if it means not having time for another game.  Also, consider the age of the party-goers, you may have plenty of time to devote to a party but the attention span of your child's age level needs to be taken into consideration when determining the length of the party.
