Your original post was at 1:14 AM Dubai time. I am wondering if the hotel was updating its rates at that time; after all they have to do it at some point and it only makes sense to do it overnight.

I, like the other posters, found 1150 AED when I did a search, but we found those prices during normal business hours of 7:50 AM, 9:12 AM and now 6:20 PM in Dubai respectively.
