Maria - You will enjoy French Quarter. Where you request to stay probably depends on what you are after.
Bldg. 5 is close to the pool, food court and in the center of the resort. Bldg 4 is closest to the food court (depending on what end of the building you are at) and the closest to the bus.
This resort is so compact that most rooms are centrally located. Some people have said that being on the pool side of the building makes for some noise so you might be aware of that. A water view might also mean a river view. In that case, Bldg. 5 has a nice view of the river and is still centrally located to everything.
The resort is arranged with the pool, pool bar, laundry, playground and hot tub in the middle of it. The food court and lobby area is at one end of the pool area and the river is at the other end. Bldgs. are either to the right or left of this area. That makes it easy to navigate and there really isn't a long walk to anything. There is only one bus stop at this resort and it is at the front of the lobby area and to the right (as you go out). Easy to find. But, honestly, there isn't a bad location. We've stayed in bldg. 5, 6 and 4. All worked out well for us.
