Swan or Dolphin to be near others who may be attending would work fine, and is generally less expensive than Disney resorts. But as between YC, BC, or Boardwalk, we prefer YC or BC. We like the set up, pools, grounds, and vibe. You can walk to any of these (Swan and Dolphin included) within 5-10 minutes tops. You are in a no miss situation as between these 5 resorts. Good luck and best wishes for your family!
