For my daughters 16th birthday which was at the end of August, we held it outside by the pool. We put up white christmas lights along the pool fence & wrapped white tulle all around lights & through the pool fence. We also put all the table and chairs together and placed tiki torches around the area. The ceiling for the patio was decorated w/hanging irridecent stars each of different sizes. We served subs & other easy to eat items. Then served the cake there too. You can get the tulle at Joanns etc, use the 40% coupon & it is very inexpensive. We also set up the stereo outside and used cd's for music. We opened the gifts inside.
