There are studios, 1 bedrooms, 2 bedrooms in every building. Grand Villas are only in certain buildings. There is a map, maybe someone can post it.
Need more info to make a suggestion.
Will you have a car?
Will you use the busses to the parks?
Do you plan to use the main pool, quiet pool or neither?
Would you want to use the counter service at the main building?
Is view important? Golf view, water view, canal view?
If
DVC reservation, is it for "near HH" category?
In my case, I always had a car and preferred Turtle Pond Road because it was quieter. Could hop in the car to get to the main building. Nice golf & water views.
