If he isn't listed on the resort room reservation, he doesn't ride the bus...it's that simple. So, I would add him to the reservation the day before he arrives....to show that he is arriving on May2...that way, he should be in the system and will be allowed to ride the bus. He will most likely have to go to the DME counter to get checked in though since he won't have a voucher in hand. They will have to print one up for him there.
