Hi Heather!
Four is the magical number for family accommodations at Walt Disney World! You can stay at any of the resorts in the standard rooms together.
Your choices range from Value Resorts to Moderate, to Deluxe, to Disney Vacation Club Villas, and even on to Camping at Fort Wilderness Resort and Campground! I recommend you compare each of these choices on this webpage first, to determine the TYPE of resort, and the amount you would like to spend:
Accommodations.
I will give you my family's personal favorite in each category:
Value: Disney's Pop Century Resort. (however, the brand new "Disney's Art of Animation Resort" opens in May 2012 and promises to be awesome!)
Moderate: Disney's Caribbean Beach Resort - we love the pool!
Deluxe: Disney's Wilderness Lodge - an escape into the Pacific Northwest - spectacular!
Disney Vacation Club Villas - Disney's Beach Club Resort - wonderful pool and within walking distance to EPCOT!
You really can't go wrong with any of your choices. It simply depends upon the preferences of your family.
Please come back to ask us any other questions you may have as you move further along in your decision-making process!
