I’d recommend YC (since you’ve already done BWI) for the Epcot resorts for all the reasons others have, but I would also second the Poly recommendation if you are interested in Trader Sams—it’s so much fun!! Plus you’d have access to the other monorail lounges. We also really enjoy the lounges as WL. Geyser Point is gorgeous with a great menu and the drinks are super good at Territory Lounge, plus if you decided to stay club level there you’d get a newly renovated room and are only a boat ride away from the Contemporary with Cali Grill (another big fav of ours).
