The Postmates is a pretty useful service that will delivery lots of stuff straight to your hotel room from your smart phone. If you subscribe to the Plus Unlimited service ($9.99 a month and FREE for the first month), all your deliveries are free and there are no additional service fees (You just pay the retail price on the shelf). I would suggest using them for liquor deliveries from a local place like Lee's Discount Liquor as it will save you a TON of money versus the mini bar or room service and it is pretty hassle free. The only caveat is that you need to know exactly what you want since they are considered custom orders. My friend ordered two crave cases of White Castle to his suite at the Cosmopolitan this past week and the transaction went perfectly. Give them a whirl on your next trip and use our promo code: RVS9R to receive a free delivery up to $10.
