Seems an unusual request for a prom but why not let the young crowd enjoy a poker tournament for a fun filled event. This can be done as a friendly , non-gambling , or rather gambling with monopoly money, type of arrangement.  And if travel is required to New Jersey then don’t try and arrange trips to the airport on your own. Hire a limo service that can provide a prom party bus in nj. The kids will love it and will be safe!
