Definitely Coronado Springs. Most of our wedding guests stayed there and everyone loved the theme and all of the activities that were right at the resort. The pool area is awesome, with volleyball courts, a great slide, and a play area for the kids. You can rent mini motor boats, surrey bikes, kayaks, party boats, the restaurant has an awesome breakfast buffet (Maya Grill) and dinner is also really good. Their fast food is awesome because it has the biggest selection IMHO of all the fast food places in the resorts. It's also cool because you have three different themed sections to choose from - Casitas, Cabanas, and Ranchos. We've stayed in Casitas and Cabanas and loved them both, but preferred the Casitas for the theme. The Cabanas are closer to the pool though.
Port Orleans French Quarter is cute. It doesn't have alot of extras - but you can take the boat to DTD which is a fun little ride. It felt like a value resort to me though, everything was really close together and claustrophobic. I prefer Port Orleans Riverside.
But my favorite moderate is Coronado Springs. We're staying there again in Dec.
HTH!
