The OP indicated that he bidded from regular balcony to spacious balcony.
In fact, both types of cabins are the exact same size and configuration, with the only difference being a slightly larger balcony. So if someone is looking for a larger cabin than the regular version, this would not be the case. It's only the outside balcony portion that's slightly larger. In my mind, it's not worth the upgrade unless it is complimentary. Just my opinion 🙂
