With kids your kids' ages, I'd recommend Beach Club. The location is very similar to the BWV, with access to the Boardwalk & all it offers. It also has Stormalong Bay, which is a spectacular pool complex...blows away the Boardwalk's pool, and I think the Boardwalk's pool is very nice. If you had a desire tot go into Epcot one night to see IllumiNations, it's within walking distance. You can rent bikes, boats etc. for that area.
