Excessive Cleaning: Getting your home company clean takes work, especially when you have little ones running about. You should expect to do some heavy-duty cleaning before the guests arrive and some light housekeeping throughout the party. Once your guests leave, you will probably need to spend another one to two hours cleaning up the mess. Kids birthday party places, however, make this process easier. While you may have to throw away things like wrapping paper, they will have staff who handle the big jobs such as mopping the floor.
