Hi Jennifer! Here is a great starter list of Disney Resort Hotels that accommodate five guests in a guest room and would be good options for a family of five traveling to Walt Disney World Resort:
Disney's All-Star Music
The Cabin at Disney's Fort Wilderness Resort
Disney's Port Orleans Resort - Riverside
Disney's BoardWalk Inn
Disney's Yacht & Beach Club Resorts
Disney's Polynesian Resort
Disney's Contemporary Resort
Disney's Grand Floridian Resort
I would recommend that you choose your Resort hotel based on your budget and which theme that you and your family would enjoy most.
www.disneyworld.com has detailed information on each Resort hotel, including themes, amenities, recreational activities, and guest room pricing. Hope this helps.
