id stay at any of the three in the epcot/mgm area.
1.boardwalk
2. yacht
3. beach
we absolutely love the boardwalk (so much so we're dvc members there). the food, fun walking around the boardwalk at night (after 9 when most of the parks are closed theres not much to do, esp. if you dont want to go to the awful thug filled pleasure island), and especially the proximity to mgm and epcot are worth the price alone.
unless youre morbidly obese, which you might be since this is america, the walk to mgm is very very doable, and downright relaxing/enjoyable. epcot is a no brainer, literally a few hundred yards away (ive always wondered why perfectly able bodied people choose to waste their time on the boat to epcot, i mean, how lazy can you be?)
so in otherwords, epcot resorts are the way to go!
