Planning trip in 2 weeks with plans to get in Cal Adventure gate right at opening to get to the Racers fast pass distribution. Son will have a voucher previously bought for his annual pass. Can he use that to get in gate at opening and hopefully get a ticket to use for the fast pass and do the picture and rest of activation later in day? If not, what's the process he needs to take to be able to get in 10:00 am opening? Can he get it all done prior to opening? Thanks in advance! Been planning our entrance for weeks and forgot about this.
