I have stayed at all of them and if you like a little quiet boat ride, either the port orleans or the french quater ( they are right next door to each other ) and can take the on charge boat ride to downtown disney ( about 30 minutes 1 way and very relaxing ) they are all very nice just depending on hat you like.
they all have free bus service to downtown disney and all parks, so either you choose will be fine

Definitely the French Quarter! My husband and I spent our honeymoon there and loved it. I love the river that runs behind it and the boat to Downtown Disney. Check out this website..
It has pictures of all the different resorts..plus pics of the rooms and amenities.

I also like French Quarter because of all the usual Disney perks, but especially because it is smaller and doesn’t feel so massive! Easier to get around, easier to get in and out. Seems a little less noisy to me.

For specific areas to choose, check this page out:

If you click on each hotel, they will tell you about all the different room options, which areas are closest/farthest and other tips.

Carribean Beach becuz the resort is spaced out, less kids, everything is so tropical, the rooms are great & I recommend you get a preferred room just to be closer to the Disney bus stops, the food at the food court is soo good especially their turkey dinners

My first choice in moderate resorts is French Quarter. I like the theming, the pool, the size of the resort (smallest moderate). I also like the boat to Downtown Disney and that you get the use of the amenities at Riverside just a short walk away. My wife and I spent our first of many Disney trips there.

I like Coronado for moderate

1 it doesn’t take all day to get to the parks. It is in the middle of all 4 parks.

2 I like the scenery/lake in the center. Something nice to look at as you walk

3 Spacing of the buildings are nice not close to each other.

4 Awesome pool.
