Hi, Beth! It sounds like you are planning a great family vacation! If you are looking for a Moderate Resort with the least amount of walking, I suggest you look at
Port Orleans French Quarter. With just over 1,000 rooms, it is the smallest of the Moderate Resort properties.
If you have decided on Caribbean Beach, you might want to request a room close to Old Port Royale so you are close to the food court and main pool area.
Regardless of what resort you ultimately choose, let the cast member know when you are booking if your mother-in-law will need a handicapped accessible room, and that she will need a first floor room close to the food court and/or bus stop. This will give her the least amount of walking around the resort.
Wheelchairs and Electric Convenience Vehicles (ECV's) are available for rent at all the theme parks. For more information, click
