Is it just the two of you? If so, I would say, no, it's not worth spending a couple hundred dollars more on YC CL. I always take a look at the extra cost and ask myself if I could do better by simply getting a grocery delivery and stocking our in-room fridge with things we like. Especially if you are mostly going to MK, YC will not be convenient. We've stayed at CR in both the tower and the garden wing and I really loved the garden wing. The rooms are large and comfortable and it's very quiet. Plus, when you walk to MK, you can walk straight through the lobby and onto the path to MK, circumventing the, usually, crowded tower elevators. Given these two choices, I would definitely do CR garden wing. Keep in mind, there are no balconies in the garden wing, but there are patios on the first floor if you have a preference for room requests.
