Coronado Springs is great!
I don't have any kids, so I can't comment on the kiddie pool area, but the main pool is something else. It's large & there's a nice slide and hottub also. The quiet pools around the property are are quiet & relaxing (and seldom crowded).
I like the laid-back atmosphere of the resort. There are tables outside by the lake where you can eat or just relax. Also, a few hammocks are scattered around the beach area to enjoy. I agree with earlier posters the resort is especially enchanting at night.
There's also a health club, arcade, and boat rental. I didn't try those, but will on a future visit. The food court, in my opinion anyway, is a notch above other resort food courts, in terms of atmosphere & food quality/selection. That automatic tip though is a turn off to many.
Bottom line, you could easily never leave the resort & have a great time.
