I agree about Grammercy's, it's just that it's close to the JET where I spend the work part of my visits. Will definitely give the Media Rotana a bash. The downtown Rotana is OK and I have stayed in the Rose Rahana a few times, fantastic food and very nice rooms. Unfortunately Sharia compliant, so thank heavens for the Crowne Plaza bar.

What's Dubai like over Xmas and new year? I normally go early January but will probably need to be there over the holidays next time.
