My views on each location. The Grandstand is our favorite for our needs But Congress Park is tempting with all the the places at Disney Springs.
The Springs (D)
Across street from lobby, food and store
Across street from Main Pool (zero entry) and Community Hall
Best rooms are center cluster, 3501-3836
but
last bus stop on park routes
The Paddock (E)
New pool and splash area (sunny, not much shade)
Food and drink (limited hours)
but
spread out
longer walks to everything
Far end is actually closer to Congress Park's bus stop!
Congress Park (F)
Near walkway to Disney Springs (Marketplace end)
A short walk to lobby, food and store
but
4th stop on park bus routes
The Carousel (G)
Small group of buildigns far away from everything, no pool.
Second stop on park bus routes
The Grandstand (H)
Good size pool and splash area (more shade than paddock)
A short walk to lobby, food and store
First stop on park bus routes
best locations are 8000s
but
9000s are a farther walk to pool, bus, and everything else
Treehouse Villas
Best if you have a car and really like the woods and layout of these villas
but
Far from everything
Shuttle bus to Saratoga Springs, must transfer to other buses
