About the T2 Multi Storey
There are two things particularly great about the Manchester Multi Storey Terminal 2: for you, it means you're just a short stroll from check-in under a covered walkway. And for your car, the covered parking means it'll be getting its own little holiday, away from the unpredictable British weather.
Upon your arrival at Multi Storey Terminal 2
Make sure you bring a copy of your booking confirmation to the car park. If your confirmation has a barcode on, just scan it at the entry barrier. If it doesn't, just put the credit or debit card you booked with into the slot. The barrier will lift. If it doesn't, or you haven't got your card, press the buzzer so you can speak to a member of staff. What you mustn't do is take a ticket or use a different card, as the machine may then try to charge you again when you leave. The last four digits of the card you booked with will be on your confirmation.
Upon your return to the car park
At the exit barrier, just scan the barcode on your booking confirmation or put the credit or debit card you booked with into the slot. If you took a ticket when you came in, or you don't have the card you booked with, just press the buzzer and speak to a member of staff. You'll need to have your booking confirmation to hand. Don't put a different card from the one you booked with into the machine.
