Yes, of course; our tickets are transferable!
The name of the participant doesn't need to match the name of the ticket-buyer. Just have the new guest check-in with the same name the tickets are booked under. We don't require you to bring a physical ticket or confirmation as proof of purchase, all that's needed is the name!
We also recommend having them bring an ID for the bar (and in some cases admission into the venue if you are attending a standard 21+ event)
