The pool and Jacuzzi overlooking the conservation land was lovely. We ordered the heat for the pool because of sister's two small children (5 and 6). We all loved the pool and Jacuzzi. The bedrooms were well appointed and the bathroom off the Master Bedroom accessed the pool lanai.
The car ride to Disney (Animal Kingdom), LEGOLAND and iFly (adults) were easy. The grocery/liquor store is within 5 min of the house. One night we went into Kissimmee to Savion's Place (Trip Advisor #1), which has a causal Floridian atmosphere (clean) and the food was excellent.
The Aviana neighborhood is newer and gated with a large Club house with a 'beach' pool, Jacuzzi and playground overlooking a lake. The Club house has an exercise center and is an easy walk from the house. One morning a pair of large sandhill cranes showed up near the lake, they were very friendly. Our visit was very relaxing and convenient for a Christmas away from home in a warm climate (60ish at night and 80's during day).
