Consider using the Advanced Check-in and Self Check-out features to allow your guests to check in online prior to your event and/or check out on their smartphones. Even if most of your supporters are "old school," allowing those who'd appreciate these shortcuts to check in and/or check out online will reduce lines (and stress on your volunteers). Setting it up is quick and easy, so it's worthwhile, even if you think only a few people will use the features - and imagine how happy it will make your supporters who just need to pay for drinks, raffle tickets and a paddle raise. . .
