It is actually near the side of the building where the Active Zone is found.
Look for Gold's Gym , as the Mail and More Booth from where you will buy your tickets is located on the same floor as that gym and is on the same side of the building.
Don't panic if you see the food court. You are on the correct floor.
If you are in Ayala Center Cebu: 5th Floor on the side of the Active Zone Area- Ticketing Centers/ Services Center near Gold's Gym- More Sevices Area- Mail and More , then you are good to go.
If you are in SM City Cebu: Traveller's Lounge-Enter the mall and go down the stairs- ATM machines on the left: and to the Booths on your right around 50 meters from the entrance is Mail and More. There , you can buy tickets.
You will be charged for around Php50.00 more than if you purchased your ticket near the port area in Pier Uno but you will be freed of the hassle of finding a taxi to take you there and carrying your luggage with you, plus the airconditioning will make your mood better.
