We stayed there 9 days this past summer. We LOVED IT! I could't tell you how far it it from Disney in terms of miles, but I can tell you that it never took us longer than 10 minutes to get to Disney. We went at various times of the day...early in the morning, late mornings, afternoons. The traffic was never unbearable and the drive was short. This was at the end of June into the first week of July.
There was still construction going on but it never bothered us because it was nowhere near the building or even the street we stayed on.
After our trip, I did read that they were building full homes out there as well,but I have no idea when those will be done. I don't know how may you will have in your party but these townhomes are pretty big.
I don't know how much more they plan on adding to the resort,but it's not that big. It was an easy walk to the clubhouse and the main pool.
I highly recommend it. It's nice and a lot newer than some of the other communities. The pool was huge and nice. There's a bar at the pool. The staff is beyond nice. I always felt safe. The guards did regular patrols. The gym was well-equipped. You will need a car. I don't know if there's any transportation to the parks but I do know that there are no restaurants in walking distance,but there are plenty(as well as grocery stores) within a 2-minute or less drive.
