Haven't used a dining plan yet... but i've read the Dining Plan with TABLE SERVICE is your best deal. Most ppl are saying you break even on the quick service plan (vs. paying cash out of pocket)
I stayed at Port Orleans FQ as a teenager. Very nice (small resort) taking the boat to downtown disney is nice.
I also stayed at Coronado springs 4 years ago. Large resort, alot more walking to restaurants and pool, but beautiful.
