Jumeirah Creekside Hotel is 100meters from the front door. It beats taking the car every day, and it's low cost.
Marriott Marquis rules with an executive lounge that looks like a 4 star restaurant at happy hour.
CAE has a list of hotels with a favorable rate. If the Marquis isn't on it, they used to give me a rate 10% above the JW in Deira.
