I don't think there's a bad area, but I prefer not to stay in the first floor with all the foot traffic going to the pools and/or parking areas.
Also, I prefer the Tower rooms rather than the Courtyard rooms, but just based on the single fact that the Towers are closer to the lazy river. The Courtyard rooms are closer to the other pool that has the water slide, if that's your cup of tea. There is no price difference between the two areas.
Here's a pic of the view I had this weekend, 7th floor, far end of the Americana tower:
