will give you an idea of what's in the area. I recently stayed at the North Star Hotel and found it to be quite nice. It was part of an air-hotel package so I'm not sure what rate I was paying but I'd estimate it at $50, not including breakfast. But for $13, their breakfast is hard to beat. It has juices, cold cereals, fruit and yogurt plus all the ingredients of a Full Irish Breakfast in buffet style all-you-can-eat.
