Are you going to buy the food or make it yourself?  Work this out well in advance. You could even consider making or baking food as one of the fun activities you do together. Snacks aren't just for eating at movies, some will help you all to stay up late too. Have chips, sodas and sugary treats to help you not fall asleep. Soda has caffeine, candy has the sugar. But be warned! While eating candy is fun, and will help, your sugar could crash, which means that you will get really tired, and basically fall asleep. A couple of hours before the guests arrive, decorate to get the theme in place. Put pillows everywhere, bring out light healthy snack food. If you want, light some nice smelling candles, especially for the spa part.
