Have a look at Google Street View for the area. It looks like some bars and restaurants are at the back of the hotel. It's a tourist area so mini markets and bars, restaurants and cafes will be open on a Sunday. The centre of the resort isn't far away either. You can get deliveries of Pizza ask at the hotel reception for the contact details for a pizza place. I don't know what the weather is like there, I am in the South but it's Summer and I would expect it to be warmer than 15 degrees.
