When entering from the casita side, rancho 6a is the first building on the left. It reminds me of a small western town with hitching posts that you would use to tie up your horse before heading into the saloon.
Ranchos 6b and 7a are next. These are three story buildings. 7a is closest to bus stop #3, which is the second stop for theme park buses.
The last building is rancho 7b. 7b and parts of 6b are closest to the Dig Site. Rancho 7b has the quiet pool and guest laundry.
Ranchos 6a and 7a are the furthest buildings out and probably the quietest.
