We are coming for 3 nights in July. We are a family of 5. I'd love to stay at Grand Californian, but do not want to risk having a family member sleeping on the floor since they won't guarantee a bed for the 5th person. So I'm trying to decide between the other two. We've stayed at the Polynesian and Contemporary at WDW. We tend to stay at the parks most of the day, we do like a quick service place onsite if possible for quick breakfasts and late night snacks. We will also swim at least once or twice during our stay. Recommendations?
