There are a lot of restaurants in the airport area that deliver. The problem is the hotels do not like non-guests coming in and out of the hotels as well as the hotels that have restaurants and "convenience" stores that sell snacks like Chips, Sodas, etc at close to double the price that you can get at a local grocery store. Those that don't mind usually have menus of local restaurants either at the front desk/concierge or in the room on the desk.
