Interesting welcome amenity at the Novotel London Bridge last week - there was a welcome note with an envelope containing a second drink voucher. They had already given me my normal voucher on check-in so I assume this was a welcome gift! Maybe they had run out of the usual water and chocolates? As I had dinner with colleagues, I had trouble finding time to use it and ended up having a quick coke before leaving the next morning.
I also was given a connecting room but someone had forgotten to lock the interconnecting doors. Thankfully there was no-one booked in the next room. I am assuming this free extra hotel room wasn't part of the welcome amenity!
