I don't think you could go wrong with either one. The studio has a kitchenette so not a full kitchen, but it does have a fridge and a microwave. It's really handy for breakfasts or snacks especially with kids. The yacht club won't have a microwave or fridge. The pool at yacht club is amazing and has a sandy area to play, but keep in mind, to get to the water slide, a kid has to leave the gated pool area and cross the main walkway of the path to Epcot. With the ages of your kids that may affect your decision. The boardwalk slide is contained within the pool structure.
