We have been at all five areas and each view from the villa is beautiful! It depends on what you are interested in. If you like peace and quiet, Turtle Pond area is great. It is near the rear of the resort and close to a pool that has a snack bar.
I like Pennisular Road area a lot although we only got a view of the golf course vs. water, but it was just a hop skip and a jump to the Hospitality House where the biggest pool/play area/Olivias/etc is. Also, it is the first bus stop on the internal bus route, so if you miss your bus to your destination, then you only have to walk to the Hospitality House to catch that same bus before it heads onto the parks.
There is a map here on this site; it is a very big resort.
Everyone has their likes and dislikes for floors, but we like the first floor because we like to be up close to the ducks and bunnies that come up to the porch; my children love to feed them. We also don't like climbing all the stairs after a long day in the park. Other people don't like hearing little footie steps above them, so they ask for the higher floors.
Don't forget to try out the jacuzzi tub in the master bedroom! It is wonderful after a long day in the park. Remember not to put too much bubble bath in it or the tub will over flow with bubbles when you turn on the jets!
Have a great trip! Hope to see you there!!! (you have a long trip coming from Hawaii, huh?...I thought we were coming a long way from Arizona!!!)
