What a mistake it was to book this place, although the fault is Expedia's as well as the hotels.
I definitely booked it for two weeks prior, when I actually needed it, but it came through as a booking for this weekend instead, and since it was non-refundable, I thought I might as well stay the night.
I originally booked it because hotels in the city centre generally don't have car parks, and I knew that this place did. What I didn't know is that parking is not included. It felt like such a rip-off. It's actually at the staff's discretion whether to exact the charge, and I had the misfortune of dealing with a jobsworth who considered ripping customers off to be a better option than treating them well. So I won't be going back.
