At the Linq shopping district You will find a drop box for Your Amazon orders. This is better than waiting around Your hotel for a package. You order from Amazon and use the drop box as the shipping address and when it is delivered You will get an alert then go to the box with a code to open it and You have Your package. Much better than waiting around the Hotel for it.
