You could ask that all the gifts be brought in brown paper bags, to eliminate the time it takes to unwrap the gifts (and to save the members the time and expense of wrapping them). You can either give the gifts out randomly (perhaps picking a gift up and then drawing a name or number out of a hat) or you could draw each member's name in turn and let that person select a gift. You also have the option of playing "bad Santa" and let each person "steal" a gift from one of the previous 3 people. When you're playing with white elephants or gifts of limited value this could be hilarious, but some people don't care for it. (You can look up the rules online.)
