We stayed in a 4 bedroom in June and liked it enough that we are going back again for 11 days in February. The pool area is AWESOME! Your kids will love it. My kids are 4, 6 and 8 and had a BLAST. They loved the slide and lazy river (which is nice because it is only 3 ft deep.) It really does look like the pictures on the website.
The townhouse itself was nice and basic. Downstairs it had a full kitchen, queen size bedroom with a full bathroom, plus another half bath. Upstairs was the full laundry with a master bedroom and full bath, another full bath and two more twin bedrooms. The only thing I didn't care for was that it was decorated very bland....all beige. Compared to other resorts we've stayed at the decorating and furnishings are just boring. I like bright and cheerful, but...it was very clean and had a tremendous amount of space for $100 a night which is what we paid. You could have two families stay in one 4 bedroom unit since there are two master bedrooms with full baths.
Also...the restaurant/bar right near the pool was very good. And...you can get a $25 gift certificate for it on restaurant.com for like $4 this week with a discount code.
It is a little further out from Disney than some other resorts, but the pool area alone makes up for it. Plus, we never hit any traffic and this was in June when a lot of kids are out of school.
Hope this helps you!
Happy planning!
