The reason I love WBC is the grills. Very easy to grill out a great dinner for a large group for less than 1 Disney Sit Down meal for 1 adult. If you are taking an afternoon break, it is simple. Throwing down some thick t-bones or ribeyes on the grill and munching on them by the pool is great. Last time we stayed, 3 1-Lb ribeyes, baked potatoes, and drinks from the room totaled $22. That is about 75% off the price of a single adult meal and drink at Disney with half the quality. It kind of goes like this. Back to the room at 2PM, enjoy the pool until about 3PM, season the steaks, throw them on the grill about 4PM, done with dinner and back to the parks by 5:30PM. All while saving about $150 for 3 people and eating much better food.
For 7, it falls into the same category. Having those easy access grills makes cooking so much easier.
