Provide Plenty of Light
One of the great things about an outdoor room is that the cool evening breeze wafting across your lounger will be so much more refreshing and natural (and inexpensive) than a blast from your air conditioning system. Make sure your family is tempted to stay outdoors after sunset by providing adequate lighting. Actually, installing outdoor lighting has never been easier. Go solar. Solar lights have come down a lot in price, and you can find them in post height, deck mounted and even tabletop models. You may still want to add some citronella candles (for obvious reasons), and maybe an outdoor electrical fixture as a safety precaution when going up and down stairs or around the pool.
