Inaccurate booking
I was told when booking a discounted two night's stay that I could use the voucher within a year on ANY 2 nights of my choice, INCLUDING weekends. I even spoke to a manager to make sure that this was the case. However, when I went to book, I found that I could only check in on a Thursday or a Sunday, not a Friday as I wanted. Beware of what they tell you on the phone, ask to see it in writing before you commit.
