I would plan on arriving at the Swan front doors by 8:45 AM. It is a very leisure walk of 15-20 minutes putting you in the line at about 9:05 - 9:10 as Guests are allowed into the park.
Walk straight through the front doors and when you get to the Swan fountain turn left, walking toward the Dolphin and exit the Swan.
Turn right on the large wide walkway go over the bridge (over the canal to DHS) toward Crescent lake & the Boardwalk. Turn right at the first walkway on your right. This is right next to the Boardwalk Atlantic Dance building. Keep walking toward the Luna Park pool and you will see the walkway on your right directly along the canal to DHS.
One you get near the DHS area you will see the new Bus area on your left and it will be very clear where you need to go to the Medical Check tent and on to the Security Check-point.
