"I was arriving very late, and leaving for a flight very early. I tried booking a shuttle to the airport in advance, but they didn't do that, should be booked when checking in.
When I arrived and tried to book the shuttle, but it was fully booked for an hour right when I wanted. So I either had to leave an hour early, or risk missing the flight. I decided to chance that there would be no queues to the check in, so I could get some extra sleep.
In the morning there was no queue for the shuttle, the driver didn't understand why it wasn't possible to book it when I wanted, and rushed me to be on time a bit earlier than I booked, so I made with 10 minutes to spare. A big thank you to him!
But really unacceptable to not being able to book the shuttle when needed, when the big reason for selecting this hotel was the shuttle service that should be available 24 hours a day. If it can be fully booked it should be possible to book it before checking in."
