Hi, Paula! There are a lot of ways to answer your question, and it isn't easy without a bit more information! I'll give you some general information, and if you have any additional questions, you know where to find the answers!
With ten people, you can opt for one of the Disney Vacation Club Grand Villas. The villas, located at all of the DVC properties, such as Old Key West and Saratoga Springs, will accommodate a party of up to 12 people, and include such amenities as a full kitchen with all of your dishes and utensils; a stackable washer and dryer; and a dining area to enjoy big family meals. You do not have to be a member of the Disney Vacation Club to book one of the grand villas, but there are not very many of them, and they do book quickly, so plan as far in advance as you can.
Another option is to look at deluxe rooms, at resorts like the Polynesian or Animal Kingdom Lodge. The rooms here accommodate five people, so you will need at least two rooms.
The Fort Wilderness cabins can accommodate a party of up to six people, and these comfy cabins also feature full kitchens. You'll also find a charcoal grill and a picnic table at the cabins. Again, a party your size will need at least two.
The All Star Family Suites will fit a family of six comfortably, and give you two bathrooms and a kitchenette in each unit. You could do one of the family suites and another standard sized room to accommodate 10 people.
Alternatively, you can look off property at rental homes in the area. There are several reputable companies in the Orlando area, and you will find at least a few private residences that can accommodate a party of ten people or more.
Good luck with your planning!
