Data on my phone didn't work (3 network was down) so I was lucky to have taken screenshot for my booking ref and guess my return flight info for the check in screen. The staff were very helpful. When I returned to collect my car, I had some sense to take a photo of the screen showing where my car was parked. Unfortunately, I didn't have the common sense to stay in Fast Park as I'd noticed the F row sign very visible beside the Fast Park. There's a F row within the Fast Park carpark directly beside the surface catpark F row. Probably won't use Fastpark again because I like knowing where I've left my car and I don't like the self check in computers because they need info from my rubbish phone. Staff were helpful and I was able to leave quickly.
