I do not have an AI hotel on the north coast to recommend, but whatever gets recommended, you can also double check by doing a search on sites like expedia.com.
Also - make sure that you read what the price is for. Some resorts tell you the room price per night for two people - other tell you the price per night for each person.
You also mentioned inexpensive, and your are a group of college students - you could also get four rooms that have two queen size beds and sleep four to a room. But if you do that, even the resorts that give a price including two people in a room will charge you extra for the additional people in the room. But they do have rooms that can sleep four (two per bed) comfortably.
