I'll let that one go since they were nice enough to allow two coupons to be used at the same time.
First I noticed that even though we are D+ our C&A balcony discount wasn't applied. I just booked a cruise though the casino and while they were nice to combine two coupons on our cruise (one for me and one for DW) I'm thinking something might of been less than desirable than it could of been.
